Tutorial please!

I coud'nt follow what you wanted to convey.

Don't use vulgar language

It looks you are impatient to receive bad reviews. For getting good reviews you should not misrepresent scientific facts. You are too young to understand all this.
If you want to compensate it by resorting to vulgar language such as: fuck, gay, shit, suck, and so on, you are wrong. You can't learn to become a good programmer by blaming others with your bad tongue.

Boring

The game is very, very boring to play. People don't want their games to be blamed, but they are free to blam other's games by sending vulgar PMs.

The game play is very simple.

The author has used some physics formulas to move the ball. If the height to which the ball rises can be selected it may be more interesting to play.

Good to kill time!!!

I played this game to kill time. I think it's OK as your first game submitted by you to NG!
