The engine used to create Milpa - known as PulpCore - is today available as free open source. PulpCore is a 2D rendering and animation framework for the Java plug-in.

I didn’t really plan on creating a 2D framework - it just sort of happened gradually over a few years. It recently came to the point where I wanted to let others take a look at it and use it for their own games.
