    The game that started it all

    This is the first of Sonic’s many adventures, and it’s a pretty good one, well, the original is good, this port is legendary! It adds two new characters, a savable game, the spindash, and more in this revamped adventure that started it all! It’s still sonic one, and it’s not the best sonic game, that title belongs to sonic mania. Some of the problems include: marble zone is very slow place and only has one route, spring yard zone has bummpers, labyrinth zone is, well, labyrinth zone, and the bombs in starlight zone are a bit annoying, and scrap brain zone has the worst music in the game. But it’s still sonic one, so its still a great game, some of the upsides are: green hill is huge and has many routes making it a great starting level, spring yard has bummpers, Labrinth zone in starlight zone have great music, and scrap brain is a pretty cool zone, I would recommend buying this, my only real complaint is the ads, but if you are willing to spend 99 cents, it’s not a problem at all! Would recommend buying!

    Time Attack Bug

    So, ever since the new update, The time attack mode has been acting wonky. I ended up deleting my game, which is fine, then redownloading and THAT didn’t fix it. Here is the bug. Each Zone in time attack displays two levels which messes with EVERYTHING. Here is an example. Green Hill in Time Attack displays ONLY acts 1 and 2. But then, the problems arise. Marble Zone in Time Attack displays Green Hill Act 3 and Marble Act 1, see the problem? This means Spring Yard in Time Attack displays acts 2 and 3 of MARBLE Zone. Then Labyrinth in Time Attack displays the first two acts of SPRING YARD, Starlight in Time Attack displays Act 3 of Spring Yard and Act 1 of Labyrinth, Scrap Brain then displays The next 2 acts of Labyrinth. Final zone displays the first two acts of Starlight, and the special stage displays Act 3 of starlight and Act 1 of Scrap Brain. Meaning I can’t even access Scrap Brains Act 2 and 3, Final, or the Special stages in Time Attack, so please fix this! This game is amazing and I’d hate to see this bug ruin it!



    I love the speedy games with sonic or captain Falcon (More than Mario). But theirs a game that I played 11 years ago I’m really requesting for cause of my childhood (I’m still a kid though) and that game is knuckles choatix. This game made me realize that I just grew up with f-zero (Nintendo) I also grew up with knuckles chaotix (SEGA). knuckles was my all time favorite sonic character even when I never knew I grew up with him ( I figured I grew with him because of sonic paradox after seeing realistic characters of chaotix but what what really jumped me was the music cause SEGA is mostly known for great music, blast progressing, and speed, so I did some research and after seeing the gameplay I gave me some flash backs. I lost the game because I broke it with f-zero and super mario world but I don’t know how I break the game though) but THANKS FOR MAKING THE ORIGINAL SONIC😃😄😁

    Need new update. Can’t finish zone.

    What’s good sega and sonic team. I love you sonic games I have them all sonic 1 2 and cd even got two copies of sonic mania for the switch and ps4 plus sonic 4 ep 1and two (y’all need ep 3 just saying) but look in scrap brain zone act 2 at the end it have a glitch in it (again) where when you get done with the zone and moving in it the cut seen right before act 3 begin the camera movies all the way up where you can’t see it and when get to eggman where he jumps on the switch to drop you in to act 3 of scrap brain zone you automatically die and have to start the act all over again. And also when you get out of the game and goes back in or restart that act you lose a life and that’s a lil uncool so can y’all plz update this app again plz. Coming from a big sonic fan since the early 90’s the game need to fix its bugs fast. And also side note can y’all plz come on out with a mobile port of sonic3k plz that game is way to cool to just let it past yea I and everyone else know by that now that MJ made the songs for sonic 3 and not in for knuckles part of the game. But at least let us download part or the whole thing to our phones and tablets plz thanks much love from one of your fans of the sonic’s series.

    It’s Still Sonic 1

    Christian Whiteheadand his team have provided the same classic Sonic game that kick-started SEGA’s mascot into the spotlight, and they have also made substancial improvements along the way. Widescreen gives you a much better view of what’s ahead and how to react, a stable framerate makes the controls buttery-smooth, and the inclusion of the spin dash makes certain sectiona a lot less of a hassle. The options to play as Tails and Knuckles are nice touches as well, allowing you to explore the levels in ways you never have before. All that said, while the game is still the classic Sonic 1, that means it has many of the downsides of the original that no remake can fix. Save for Green Hill, the overall level design leaves7 something to be desired (Marble and Labrinth are especially boring), the bosses are beyond easy to beat, and the special stages give me headaches from two angles; one comes from the constant spinning of the stage, and the other comes from how downfight frustrating they are. Overall, the downsides are mostly mostly mitigated by the touch-ups from mobile port, and it’s worth trying out if you haven’t played Sonic 1 before.

    Almost awesome

    Being the lame-o that I am, I’ve never played the original Sonic the Hedgehog, so seeing that there’s an app where it’s free to play made me excited! I did see the hit and miss reviews which kinda had me nervous, but I got it to see myself. The number one complaint I and the others have is the ads. My lord. Press start, ad. Start stage, ad. End stage, ad. It takes away from the experience. I get why you have ads and that’s fine, but it’s how much you get in so little time that’s aggravating. The other thing is the controls. Now I know it’s hard to take a game that had a controller and put it on mobile, but sometimes the run control can be iffy. It just doesn’t respond sometimes. But the ad thing is what’s got me most annoyed. Really other than that, it’s a cool game. For someone like me who hasn’t played it, I like it. It’s almost awesome. Just needs a few fixes. I’d download it and try it and see if you can take the ridiculous amount of ads and iffy controls. I mean the game itself is fun. Just little stuff that takes away from it.

    The game’s great but...

    I love Sonic the Hedgehog. He’s my favorite video game character of all time ( under Mario) and I would’nt have known who Sonic was if it weren’t for these games. I love these games but here are a few thing to fix. 1: remove the amount of ads. I know there’s nothing wrong with a couple ads but you if I have to watch an ad before the game starts, I think there’s a problem. In fact, sometimes the game will crash because of an ad. If you can fix the amount of ads in the game, that’d be great(and yes I know I can play the game with no ads) 2: bring back debug mode and level select. Ok so this one’s is jabbed at Sonic 1 and 2 like the other but don’t question why I didn’t mention Sonic 2 on the other one because you should’ve implied that. Anyway, one of the fun thing about Sonic 1 and Sonic 2 is the level select. It was one of the things that got me going back to the game was the level select. Which is why I was mad when it was removed. I loved goofing of in the game. I didn’t know why you guys removed it, so if you’re reading this, please bring back the level select. So that was all the things that need to be fixed or come back . Like I said, Sonic 1 and Sonic 2 isn’t bad, it’s just missing stuff like a multiplayer mode ( I know I didn’t mention that but I thought I mention it here), and besides you’re the people that made Sonic rom hacks that were amazing, so I believe in you guys so please keep supporting Sonic 1 and 2.

    A Blast To The The Genesis Era

    Disclaimer: I played this game on iPad so I don’t know if the iPhone is harder to play on Right off the bat, this game is a ton of fun. It is challenging and the frustration only comes in a few places (Marble Zone). Another cool addition is an addition of 2 characters that weren’t in the original. Tails and Knuckles. I find it really cool that you can tackle the game in a fresh new experience. The characters need to be unlocked, which adds to the replay value. The save system also helps, so if you die, you don’t go back to the first ever level. There is one glaring issue though, and that is ads. If your anything like me, I don’t like in app purchases. I would have much rather had payed for the game, with no ads, instead of having to pay to get rid of ads, after downloading the game. Otherwise this was a great game, that I had a ton of fun with.

    You can lose interest

    I am a Sonic fan and a Dragon Ball Z fan so when I first downloaded this game I was very excited. I was getting ready to go to somewhere (I think) and I was playing Green Hill Zone act 1 or 2 or 3. I played it for some time and, over that time I lost interest. I went to play SonicDash (I think I did) and later I uninstalled your Sonic 1 game. I would recommend that you do more things to keep this game interesting. You could add a Super Sonic and Hyper Sonic transformation and you could make it so that you, well if you don’t add Super Sonic or Hyper Sonic you can make Sonic invincible. When you get the invincibility power up you become Super Sonic. You can make a way to cheat and get all seven Chaos Emeralds without having to work to get one by adding a glitch that tells you how to do it. You can add Red Star Rings. You can add a way to get a Big Red Star Ring and when you jump into it you get a special stage where you can collect Big Emeralds. And when you turn Super Sonic the Rings turn into Red Star Rings that can help you go Hyper Sonic. I am only giving this game 2 stars because I lost interest pretty quickly. This is recommended for those who like to get bored 😐😑😐😑😐 pretty quickly. Other than that the game is pretty good. And also I am thinking about installing it again. Good job 👏🏾!

    The new update created more problems than it fixed

    When I saw that Sonic 1 was receiving an update, I was excited as I thought that they would fix the glitch where the Game Center achievement “Beat the Clock” would not be distributed. However, after the update, I was shocked to see that it created more problems than fixes. Not only was the Game Center achievement still broken, but the update also added multiple new problems. The file select now shows 7 Chaos Emeralds, yet only 6 can be acquired through normal gameplay. And if the player goes into a Giant ring at the end of Act 1, after the special stage ends or they collect a Chaos Emerald, it takes the player to Act 3 and skips Act 2. Also, a completed file now says “Special Stage 1”, but selecting the file takes you to the “Stage Select” screen. To make matters worse, the Time Trial mode is completely broken. Each zone only contains 2 acts instead of the 3, and different zones will be merged with other zone selections (Ex: Green Hill zone Act 3 in the Marble zone selection). I am very disappointed with this update for Sonic 1, as I was hoping that things would improve much more as time went on. I hope that these issues are resolved as quickly as possible.

    Impossible glitch on iPhone XS

    There is a glitch in Spring Yard act 3 that makes it impossible to pass the act. After beating Robotnik and opening the animal capsule, Sonic runs off the right edge of the screen and dies while the animals are jumping out of the capsule. This was not a one time glitch. This happened three times in a row and I got a game over. I also noticed that you can see the edge of the game window during the end of special stage score screen. I believe the edge of the game window does not extend far enough on the iPhone XS screen, allowing Sonic to run past the edge of the game window and fall off the right edge of the level and die, or some similar behavior. A previous review addressed the same issue and the developer response was the dev tram was aware of the problem and working on it. That was 8 months ago and the problem is still present, despite a game patch coming out one month ago. As a software dev myself, I am embarrassed of such unprofessional work. Please patch this glitch so I may update my one-star review. Addendum: on iPhone SE, the game runs super-slow, like at 75% speed. What is with all these bugs?

    Game is great, the port is terrible

    Sonic The Hedgehog is a great game. This port, however, is terrible. You can get all the way to Scrap Brain Act 2 and that’s it, due to a glitch that has been present for a long time, you’re not going anywhere but to an eventual “Game Over” screen. That’s only part of the big issue with this port. The game has been broken many times before, and what happens next? You wait forever for them to come out with an update to fix it. You may email SEGA informing about said glitch, and get the same automatic reply within a week. We finally get an update that I hoped would fix the glitch that makes it impossible to progress to the final boss. Still broken. SEGA, learn from your past mistakes and fix this. The fact it took so long for an update that ultimately didn’t fix the game like it did last time is unacceptable. If you want a classic Sonic game for your device, get Sonic The Hedgehog 2. If you want this game, pick a different platform (excluding the GBA, because, well, you know), this game is everywhere.

    Simply Terrible

    I would enjoy this game a lot, if I actually got to play the game! There are so many ads it literally crashes my game before I even reach the "Start Game" button. I can hardly complete a stage, because whenever I try I always crash and have to restart my game. It's so bad that if an ad is over 10 seconds long it goes right back to the starting screen. Like seriously SEGA and Christian Whitehead you can do much better than this. I managed to beat the game, but I no longer want to play it ever again yet alone put my hands on this game ever again when all I know I'll be getting is ads all over the place. Also why does anyone need to pay to get no ads, I wouldn't mind the ads if they didn't ruin the game and the overall gameplay experience, but buying no ads in this game seems almost mandatory with the fact that there are ads everywhere. Honestly, if ads are ever used in games it should be done correctly and should never affect the gaming experience, and this is a perfect example of how not to use ads in games.
