Below you can download the source code for Windstille, the 0.2.0 release should be a useable techdemo, its a bit playable (one level, one type of enemy) and should give you an impression of how Windstille might look like. The 0.3.0 release is much newer, but not really playable, its just a pure techdemo. Win32 releases always lack a bit behind. The static-binary requires a working OpenGL installation, glibc version shouldn't matter.
