Possibly the Hardest Game.

This wickedly difficult game... it's just too hard! Basically you're the RED square, you navigate the level with the keyboard to avoid the BLUE balls, and reach the other side of the GREEN patch. Some levels require to pick up the YELLOW ball before you can reach the other side. There is no time limit, the high score is defined by the number of deaths at the end of 30 levels. Sounds easy? Wait till you try it!

I gave up at level 10. -.-
