The game is written in Haskell and is built using the Haskell Cabal. It was written on OS X 10.9, so there is no guarantee that it runs on other platforms, and even on OS X 10.9 there are a few things that need to be done:
1. Upgrade to GHC 7.7 because 7.6 has linking errors on OS X.
2. The GLFW bindings are out of date. They bind to GLFW 3.0.3, but 3.0.4 has some important bug fixes that can be gotten from source.
3. SDL and SDL-mixer (for sound that I didn't get to) are also required, but you have to have sdl-config in your $PATH and SDL1.X installed exactly in /usr/local/lib
4. Lambency (a dependency) requires a newer version of the Haskell OpenGL bindings that supports mip-map generation, so those should also be taken from source.
Once everything is in place, the standard cabal way of installing and building is done:
Programming - Pavel Krajcevski
Design - Jonathan House
Art - Daniel Gallagher
Music and Sound - Will Blackmon and Isaac Hinkey
