Sporktris is a clone of Tetris-clones. It doesn't add anything new to the gameplay, it simply tries to do all the important things well.
Technical Details
Sporktris is written in C, using SDL for graphics and input (for easy portability). It requires SDL, SDL_image and SDL_ttf to build.
License
Sporktris is Free Software released under the GPL. Donations are totally unexpected, but greatly appreciated.
