My only complain would be a rather minor one. At first glace, it appears we would crash by flying over the brown colored 'building like' objects, as soon as I figured out this isn't the case, the game was incredibly fun. It's a nice, simple creation.
I enjoyed this game . I just wish that it had some power ups .
I'm not very good at this type of game, I only lasted 168 seconds. BUT! I had fun!
I really like the Idea of the flash, Its a quick game
The only thing that annoys me a little is the lack of a soundtrack, and just the effects. Also you can barely see the "power ups" when you're fast (speed over 15) Because the "camera" don't really follow the plane... There are no problems, really, but these are just two things I'd change. :3
