5 stars: It was really fun, but there were some issues I found while playing. There were a lot of ads popping up, and I play on a PC so when a certain ad pops up, it gets cut off so I can't see a large chunk of the ad (including the X and the skip buttons). The shield after reviving could last a few seconds longer too. But other than that, I love the game.
5 stars: Still love this game after 2yrs of play. Some levels harder than other and takes time to complete. I like doing the missions, i can get coins and parts for ships and drones to upgrade so i can beat those hard levels. An occasional glitch here and there, but i still give it five stars, cause once i start i have a hard time stopping.
4 stars: The game actually improved a lot since the time I first installed it. There are more events and fewer crashes.
3 stars: I like the game but the ads are fraud. countless times I've watched ads and have not been given my reward. now it's become automatic. dont waste ur time with the ads. they're a scam. please fix this...update... I appreciate your quick response. just hearing that u guys are working on it will keep me playing. the game is great if u like old school arcade. definitely recommend
2 stars: This game should be great, but it's not. It gets too hard to fast. Good luck if you get past level 20. Power- ups run out too soon, or you get them from the last enemy and they run out before the next wave. There are some UX dead ends. Not very clear how to level up...
