Thank for your welcome and your advices.

I think you are right, the download is too big. I'll had to compress the music (16 Mo ), but I don't find a valid free mp3 library for delphi.

Concerning the gravity, I'll check my algo, because, it's true, I'm not really satisfied by the ball movement.

For the end game screen, It's a pretty nice bug ! I'll investigate this.

Then, concerning the graphics, you are (again) right the character is a poor try ! I'm not an artist

So, I'll check my work back !
Whatever, thank you for your opinion.
