Dudeball is a 2D arcade game which is written in C. The rules are damn easy, almost as in soccer.
You have to catch the "dude", a neutral player, and pull him to the enemy's place to get one point, if you have 5 points, you win.
It has a PvP and a Computer vs. Human mode, but only two players can battle each other.
The main menu is in English, but the in-game messages are still German, I will change this soon.
You have to install libSDL libSDL_image and libSDL_ttf to run this game.
