The game has just one small problem that breaks the whole game and that is the moving of the ball is relative to the ball I don't know were is he facing, if the movement was global (When I press Left it needs to go to the left and it should not mater where the ball is), but over all it is a great game the music, sound efects, the puzzles are awsome. It is realy easy to understand what to do. I just turn on the game and I just get it.
If i remove the bad movement it is a awsome game :)
