4 stars: Great game to pass the time. Would be better if there were more upgrades to work towards. Game gets too grindy and stops feeling rewarding after a while without them. I would suggest more ships and being able to upgrade bullets as well. Maybe some more shooting features too? Great idea just needs a little work. Cheers!
3 stars: It was fun for a few hours. -lots of ads. -all the levels are the same. Level 20 is the same as level 1 but with higher numbers -after you unlock all the premium ships and abilities, there's no more to the game. Further progression at this point is just shoot fsster/harder +was fun for the first few hours until you realize that was the depth of the game
3 stars: I mean, great concept. But along with the traditional grinding cliche, the numbers go up evenly with the upgrades, and the level formats stay the same. Cool time killer for the first 3 levels, but after that it gets stupidly repetitive. Also, ads on every stage, of every 3 stage level. When you die, if you win, if you get an extra upgrade, etc. So 3 stars mainly because of the ads.
2 stars: The game is a fun time waster. The main issue is all the ADs! And not short ADs. You get the full 30 seconds and then you have to wait an additional 5 seconds for the 'X' toa appear so you can close it out. I was tempted to purchase the No ADs, but the game isn't worth the $7 they are asking (in my opinion) So, if you don't mind a ton of ADs after every level, death and the optional bonu...
