Hi! I'm not sure what you're trying to run the game with but unfortunately it was made with our custom engine Sugar which is not available to the public at this time. I shared the source files mostly to comply with the Ludum Dare Compo rules, and so people can have a peek at them, but there's no way for you to actually build the game sorry.
That being said, I'll be trying to provide a Mac version myself soon, and I will add a Linux build today as well!
