Milk Quest: Half & Half is the worst platforming game in existance, and now it's coming towards YOUR local git repository!
If you're looking for the current stable build, you can get it here.
You'll need_ Gamemaker Studio 2_, or it's demo in order to build the game. Read about cloning the repository here.
If you really want to use this code for some reason, talk to me first because the codebase is awful.
