It’s a fun game
I appreciate how they don’t have constant forced ads; rather it’s an optional ad that gives you a gift. The in app prices seem steep, but I see it as a necessity to help keep forceful ads at bay. Or you can just stay as a Free to play player. It’s a grind, but if you’re here, then that’s what you already want. An idle TD game that feels almost infinite, taking up 10 minutes of time or even hours. With a variety of ways to power up your monster using Essence or gems, also prestige points. You gain essence by beating every 10th level and from bosses I presume, my highest wave is only 190, so I’m still very new. Gems can be earned from completing challenges, while Prestige points can be amassed by going up in prestige. Also there are buyable bundles/packs of goodies. Good game. Edit/tip: save up gems for 2x gameplay speed. It takes about two and a half days to earn 500 through achievements, and gift ads, it might even take less time tbh. Since I wasn’t too avid about playing, but I did let it play through the night as I slept. 100% worth it
Exceeded my expectations by miles
I’m a sorta weird idle game lover, and I’ve played a lot of these. I went in thinking i was gonna get a basic clicker-style, high numbers, waiting and watching ads. Man Im telling you, this app is WAY more than that. There is so freaking much to this game. A dozen different currencies that are each exiting to collect. Super addictive gameplay, you won’t be quite as idle as you might think lol. Even a weekly tournament that everyone has a chance at. The developers have put some major time and care into making this super legit game. The game title is just clickbait, don't think this is your generic idle td game. A must play for idle game lover and td lovers. To the devs: i appreciate that you can earn most of the stuff in game for free, however i do sometimes enjoy the rush of putting a few bucks into a game to get something special. But most of the premiums are quite pricey. I wish there were some more budget premiums for sale, thats all.
Fun but needs more communication
I love the game and everything about it, the only thing I would like to see is maybe clans, some sort of communication box to talk to people, and maybe some sort of world boss level where the monsters are extremely hard and the boss at the end has more hp than most people can kill. The whole community could work to kill it and rewards given to the most damage and or clan damage. It just feels empty when getting on would like people to talk to. I would also like the function of it working levels while the game is closed. Skipping by 5 up to 75% of what you had before takes forever at late game and not everyone has time to have the game up for 3-5 hours a day. Other than those ideas the game is still entertaining.
Found a Essenes bug
I had around 2100 Essenes I used 600 on an upgrade and I went down to 894 ish Essene now I’m know I’m not good with math but I know that’s not right😂 I don’t think it’s that big of a deal but a tournament is coming up and I want to be prepared the best since I’m very new to this game also, the game crashes every now and then but that might be because I’ve been on it for 2-3 days without getting off and I’ve had it for I think 3 1/2 to 4 days so I would love it if this doesn’t happen again but it’s a bug I’m sure other players are having as well, thanks.
Tank you developers!
Great game, super addicting! It brings in strategic elements as well as the game is never just extremely tough in one part of the game like most other tower defenses but it just alway has this fluid motion to it, you’ll never get stuck in one place for too long which is why the game is so addicting. It also doesn’t just take everything in the game from other similar games because it has tons and tons of original content for hours of fun every day. Thank you for creating such a great game!
Good game with great potential
So I just dowloaded this game yesterday and it’s very addicting. Only problem I have is that the the only thing you get while afk is gold. The timers don’t reset or continue to count down unless you’re in game. Now the skills are one thing since they don’t take a long time, but things like the cargo carrier which take about four hours are a different story. I don’t know why the devs would think people would want to sit in game for 4 hours or more. Now I know there are upgrades that minimize the amount of time needed for the ships and drones but the fact that you have to sit in game for like 12+ hours at least to get those upgrades is pretty ridiculous. This game is good but could be much, much better with one fix. Besides that the music, characters, and upgrade system along with other things make this game very good. This game has crazy potential and the only thing holding it back is that the game isn’t very much about the afk aspect since you have to sit there for hours to actually get good stuff. Anyway highly recommend but be ready to put in a good amount of time if you want to make it in this game.
Pretty Darned Good
This game has a lot going for it and it is very fun. I know people like the optional adds, it is colorful and has good depth. I also like the different maps, but the one real issue I have is the game is more Idle Game than TD. Like really, a heavy grind and in the long run, prestige’ing over and over and over again for permanent upgrades matters more than where you place your towers. Like there is very little strategy/td there when you think about it. There is a serious lack of towers as well. Essentially 12-16 total because many are just the upgrade of the lower version of it and they don’t change as you level them. Don’t get me wrong, it is fun and I am still playing it, but it is definitely not the best (hence the 4 star rating). Also there is this bug where your tower has targeting of the “furthest in the maze” but sometimes they definitely do not shoot the furthest. Overall, good game, but it is just missing something..
Great app but needs some small tweaks
The app is great, and I love playing it with so much free time now, but there’s a couple things that can use adjusting. The app layout isn’t compatible with the iPhone 11 screen size, it’s a little big and the bottom menu buttons are too small to tap on. My hands are relatively normal size by the way. It’s even harder to tap on with the home button bar blocking over Collections, Premiums Shop, and Challenges buttons as well, so maybe some space at the bottom of the screen to avoid existing the app. Also the menu that pops up after you tap on a monster blocks other monsters on the bottom half of the screen and that can be annoying when leveling a monster up on the bottom half of the map. Other then that the app works great and I can’t get enough of it.
Glitch
Great game I would play it a lot last year and got really far. I just downloaded it again the other day and linked my progress to my phone and everything was there. Though, when i try to prestige a screen appears telling me Im going to Cursed Clouds; nothing happens. The white screen sits there. So i exit out of the app and go back in and im back. I received my prestige points but didn’t reset my progress. Sort of annoying because i cant get essence or make any real progress unless theoretically I prestiged constantly and got a lot better stats using the points. That would be cool but that’s not how you play the game. I hope someone can help me fix this glitch.
Most of you misunderstand
Literally. Like most of you one, two, or three-star this game because you don’t pay attention, lol. Hauler and drone timers DO count down while offline. RNG makes this game go ‘round. When one element starts doing better, focus on your best tower and diversify where you can because you will regret not doing so. Artifacts will eventually be the DRIVING FORCE behind pushing waves. That is all. This is an amazing, long-lasting game that has yet to feel too grindy for me. I literally only rated four stars because it crashes a lot once I start hitting the 700th wave or so. Other than that loving the good work, thank you!
Good game but some deal breaking flaws for me
Overall it’s a decent TD game, I’ve played it consistently and for the most part it doesn’t seem like it’s locked behind micro-transactions to advance far. Buying gems will help accelerate you getting to higher waves but by no means are necessary to get their. The main issue I have with this game is how much time it takes to get to where you were after you prestige. I saved up 500 gems to get the 2x speed perk (all gems earned through playing which is nice) and even with the 2x speed this game takes forever once into the early 100 waves. This to me wouldn’t be an issue but in order to progress through waves you need to have the app open. The “idle” aspect of this game is you earn gold while not playing. If they made it so you could progress through waves with the game closed, like a true idle game, I would give it 5 out of 5 stars. Having to have this app open for 2 hours straight just to get back up to wave 400 is just a deal breaker for me.
It’s okay
This game is cool in theory, and would be in practice, however there’s a problem that makes gameplay really difficult. Aside from the tournament timer, timers don’t countdown. Your spells/drone swarm/cargo carrier don’t refresh when you’re not in the game. This becomes a bit problematic since this is an idle game, a game that you don’t really need to have open all the time. The game also doesn’t progress while you are not in it. Waves of robots come, but if you’re not in the game, you don't go on to the next wave, you just sit there and collect money, which isn’t much in earlier waves. Overall i want to like this game. It’s really easy to not pay money, and if you do spend a little bit it can give a pretty good edge over the idle part of the game. However with the game not really working without you having the game open, it loses the “Idle” part of its name.
Not really idle and greedy as hell.
I like idle games they are fun things to play during the day. This game isn’t really a idle game. Only way to make progress is having the app open at all times. The minute you close the app you stop making progress and make small amount of gold until you open it back up again. On top of that is the greed. This app wants to charge you for everything. Now I don’t mind spending money on f2p games I usually do. But the prices here are insane and the amount of things to buy with real money, in game currency, and bundles are so over the top. There is even a tournament where people compete to get the highest completed wave and you can pay to boost damage or whatever in the tournaments. It’s shameless and expensive. Don’t bother with this game I tried it and wanted to love it but it’s just too many issues to fully enjoy it.
Too slow, not enough player participation
Overall concept is good. The game just moves so slow. You just watch as monsters creep slowly along in waves that take forever to advance through. An ad can be watched to speed up the game but lasts for only 2 minutes. Eventually towers get expensive to upgrade and you do nothing but watch and wait for money to come in. Becomes incredibly boring. Restarting currency also does not go far enough. Spend hours upon hours to reach the respec point to get a handful of small upgrades and then do it all over again. Also in game purchases are poorly priced. No way I would spend what they are asking, it’s way too expensive for what would be received.
