Canabalt Maybe a Highscores Board?
The game is really cool, with great graphics, up to todays flashgames fashion with pixel sprites and limited palette. That's great, I love that style. The music is really fine, I loved it. And the game itself is really nice too, I really enjoy playing it. The only thing I think could really improve the game is a Highscores Board. It would add competitivity to the game, and I'm sure more people would play it more times, cause if you like a game, you want to, and try at least a couple times to get the highest score.
