Hey, a fellow Gamemaker! Man, I just know this game will cause me some sleepless nights... great stuff!

There's only one little problem, the ball should have a maximum speed. If you press Space and watch the ball bounce up and down in the very first room, it eventually breaks free, because it travels so many pixels per second that it skips over the blocks.
Btw, tried the little secret in the help file, but nothing happened?
