4 stars: Fun game. No ads but what runs under the menu. I wish all games were like that. Game is addictive but not over whelming. Been playing now for a while and my biggest complaint is that it never really gets hard. Just time consuming. Would like a challenge more than just wasting time. I would recommend the game for a short time. Long term I think I need a harder game.
4 stars: Great game and I had a lot of fun playing it. At level 153 .You can play without spending any money but you must watch a lot of ads to get more stars which is money in the game. If you are going to purchase consider the $13 package which will give you complete upgrades and weapons. No instructions are available, therefore try all weapons as you level up.
3 stars: Controls are for small fingers, you have to lift finger from screen when moving left or right, if you slide finger motion won't change. Game is monotonous, it just adds one sub to the next level you don't need the special weapons. Was kinda fun for a while.
3 stars: It's fun, but the game cheats. You see two missiles rising, so you position your ship safely between them, but suddenly a third missile appears at the last moment. Also, there are no instructions!
2 stars: its been good until recently. just keeps crashing for no reason everytime in the middle of a round. I'm at round 101. just unistalled after 10 times crashing. not worth the trouble
