Welcome to fun64 the super simple super lowrez single file game engine powered by gamecake.
Try the live html version of the example projects here, this site can be fund in the pages folder.
Be sure to clone with submodules as the engine binaries live in a permanently orphaned branch. The recomended way to do this is like so...
git clone https://github.com/xriss/fun64.git cd fun64 ./git-pull
The same also needs to be done when you pull updates, so remember to use the git pull script provided or your bin dir might get out of sync.
