Cat-n-Cookie

-is a game created for an university project. I, without any knowledge in game programming, wanted to create code from a beginner to beginners. -it's about a cookie (brown square) which jumps over black squares (cat), the score is shown under the playing field. The score is also been shown when you died. -the game works... -... but there is an unwanted scrollbar which makes it almost impossible to jump correctly (my record had been 8 times). If anyone knows how to fix that nasty little bugger, feel free to correct it!
