The game itself is really fun, and it's a different take on TD. The only reason I gave 2 stars is the ads are SO LONG and very frequent. They are "optional," but really, you can't beat the level without watching. Some ads are 2 minutes long. If the ad is short, they double it, so you must watch 2 ads. I understand the need to make money but i am watching ads as much as i am playing. This could easily be a 4-5 ⭐️game if the ads were shorter.

Fun game and easy to learn, but the RNG of the cards is maddening. If you could customize cards you like and ones to not use, that'd be amazing. Otherwise you get stuck on levels like Normal 15 which seems impossible unless you get the perfect cards AND targeting RNG. Between that and the gear system being very hard to swap from mission to mission, it needs some fixes before it's worth a higher star rating in my opinion. Otherwise this is just a grind fest.

First few levels are fun but this game is boring after that. Everything is ridiculously expensive and the ad lengths are extreme. Want 2x speed in missions? $50 bucks. want a starter pack? $30 bucks. Want a single extra power in a level? 60 second ad. Can't recommend this to anyone.
