Decent game, be proud

Graphics- I like the graphics in this game. There's only 2 colors, but still you managed to add smooth gameplay and some nobility. I like it.

Sound- none. If you make a sequel, be sure to slap in some sfx and music.

Gameplay- fun level design, cool obstacles, and checkpoints make this game fun enough to play.

Story- none. at least you put in instructions...

Interface- simple. the mouse.

Overall, nice game. Congrats.

P.s. I can cheat. All I have to do is pause, drift my mouse to a checkpoint, and unpause. You should make it so you can only read the instructions on the first level.
