So I’ve been playing this game for years and it’s my favorite to play on my phone. There are ads but the great thing is that you don’t have to watch the whole thing. You can X it out after a few seconds. Also the game is free and there are not any games that are free nowadays so bonus points. I do wish there was an update to make the game challenging since after 300+ levels it gets kind of repetitive but overall great game!Edit: Pleaaaaaase add more levels!!! And weapons and places please

One of the best games ever. You don’t immediately get bored of it like some other games. The only downside is that after about district 150 the level start to get repetitive. I am past district 500. It is still extremely fun, but I wish they could add some new boss levels and aliens maybe even some guns too.

The game is good. Really good. However, most of the gameplay relies on making well-timed swipes up and down to avoid enemy attacks. The big issue is that sometimes the game doesn’t detect your swipes, which is a huge problem when you need to jump out of the way of incoming fire and your character just ignores you. I’ve had times where I’ll swipe up 5 or 6 times in a row without any response from the game. I don’t have the same issue with other games and I’m not the only one with the same message in their review. I still play it, because it really is fun, but it needs some debugging.

Spend $2 and get a ton of upgrades to make this game even more fun than the beginning. Highly recommend playing even if you don't spend the 2 bucks.
