Symbolica is a remake of the C-64 game of the same name. It is targeted to the Linux-based handhelds gp2x and N800, with a Linux/386 binary also provided. It should compile under any operating system supported by SDL, SDL_image, and SDL_ttf. The symbols on the screen represent a numeric value in the order they are displayed on the right. As you move over a symbol, it decrements to the next lower symbol or disappears. Your job is to clear the screen and move to the 'E' symbol.
sge2d, also known as SDL Game Engine, is a platform-independent 2D game programming framework for C/C++ programmers with the least possible dependencies for easy porting and with a focus on easy API calls and the requirement of commercial programmers. Major features include animated sprites with exact pixel collision detection, A* pathfinding, encrypted files, and more.
@bequick: It is not open source, as it clearly says besides the big label named 'Licenses' which every software on freshmeat has (yeah i still call it freshmeat, the new name sucks). You should remove your rating, it is not fair, to rate software down for having obvious trouble with your eyes.
