What is it?
Topkata is a OpenGL game written in Haskell.
darcs get http://home.arcor.de/chr_bauer/topkata
There is also a windows binary with sound support: topkata-0.1-bin.zip.
Maybe you need to install openal.
At least under Linux/x86_64 there are problems with an older
version of openal. If it is
used topkata segfaults immediatly.
The openal-soft package
solves the problems.
I also wrote a browser text game CommunityStory in Haskell.
Until now just in German...
