K-Stet is a small game I wrote in OpenGL a while ago. It's not really finished yet and will probably never be... The source code is given with the game. You'll find bellow different versions of the game. It's build on the OpenGLUT framework and uses SDL to read the images files so it shouldn't be to hard to compile it on every reasonable platform but only the win32 binary are given for now.
The aim of this was to test a gameplay idea that turned out to be not as fun as I expected. In the game you control the rotation of a board on which drop colored drop of water fall. The drops should be lead to the hole with the same color. Try it maybe you'll find it more fun than I do.
