I brought this one yesterday, it looks pretty simple, but I like simple games, so I spent 1 buck on it. You control a space fighter to destroy the meteorite, you got 2 weapons, Machine gun and missile, the meteorite will keep showing up, just try get high scores. So far my best record is 152127. Well, I got say it desn't have much contents, just one level plus a fine game play. But I like it, doesn't cost me much energy to think, just reaction, So I can play it in subway or office. Anyway, you can get it here if you like simple games too: http://itunes.apple.com/us/app/star-sweeper/id504497246?ls=1&mt=8
You should give it an iTunes review if you like it. I'm sure the developer would appreciate it. It has none.
