Canabalt v2.0
Why did I puch such name to this review?
Because it's true! The idea is about the same, but the developer(s) have improved it, giving a reason to play it, by adding achievements and upgrades.
I would have give this 9, but since from I've seen many games like that, I'll give less.
The graphics is cool, but chiefly, it's SMOOTH.
There's nothing worse than playng a game at 15FPS.
Howver, the game is really well done, keep working like that and you'll get even better.
