Easy in cheating =(
The game is done in a good, formal style - it's nice and smooth. I like it.
Music suits the game deeply.
BUT! There is a bug that ruins all the fun. The bug allows you to cheat easily - move mouse of the player area and re-enter it at the other edge - WHOA! Teleport!
This bug is related to all games with simple startDrag() function or with smooth ones that use mouse coordinates for the ball within setInterval().
Fix it - and it will be great ;)
