Well done Simon. Very nice game.
Couple of things you might want to tweak/fix:
Seems to require you to be over exact on where you sit the ball in the finish circle to end the level.
I noticed the first credit page isn't numbered correctly: it says "1/1" when it should say "1/2".
As regards difficulty: I played on medium and found it frustratingly hard with the mouse (for my first couple of goes), but satisfyingly hard with the keyboard. Hope that helps you tweak it.
All the best with it!
