I’m not too far in but it’s fun. It’s difficult enough to where you can’t sweep every level but you can still win. I love how all the ads are optional. It’s definitely easier if you pay but so far I haven’t had to spend anything. Will update if I hit a wall Pretty good so far I’m not too far in but it’s fun.

Game offers a lot of options for more passive or active playing. Simple and extremely difficult; lots of strategy, failing and trying again, luck of the draw mixed in, and thinking long term. Lots of fun, very cool artwork and animation with chill music and SFX. I would definitely recommend it. FYI: you can move your gunner dude if you want to but, it is not always advantageous.

I downloaded this game and it is really fun and exciting but it is sooo hard. Just cleared level 5 finally but that was after buying a power up and replaying previous levels several times to level up. Enemies are stupid strong and hard to kill. I recommend the game but know you will have to work at it. Game is super fun, but incredibly hard!! I downloaded this game and it is really fun and exciting but it is sooo hard.
