Nice platform game.

I would make the ball move a little faster, but beside that its a great game!

I increased the speed, however, tell me if there are things that you believe should be improved.

Nice little game! The tutorial level shoud let you do things with the powerup
And there should be a restart button, when you messed up.
Maybe checkpoints?

Oh, I forgot to add a sign for the restart button which is "R".
Checkpoints are a really good idea!
Maybe I'll "The Dot 2.0" for the Ludum Dare #22.
