Let's take a walk is not really a game. It's rather a toy — just a demo of what I can achieve with my VRML + OpenGL + OpenAL code (read: 3d graphic and spatial audio fun).

Note that to hear game sounds you should first install OpenAL. Windows users don't have to do anything, appropriate DLLs are already is the archive.
