Port of Notch's Minicraft in a functional way

Funcraft - a Clojure port of Minicraft

This is a fun little project to learn how to rewrite an highly imperative Java program in a functional way in Clojure.

Markus Persson (alias Notch, known as the creator of Minecraft) created Minicraft in just 48 hours for the 22nd Ludum Dare Competition. Despite the short development time it is a completely functional and high quality game. At the same time it is small enough to be ported or enhanced in a reasonable amount of time. Indeed lots of ports exists already (see the list below).

While he released the source code, he didn't assign any license to it, so technically the original source and artwork still falls under his copyright, but he gave permissions to make clones under a different name.

Since this is just a learning project to see how to rewrite a highly imperative OO program in a functional way in Clojure while at least trying to keep similar performance characteristics as the original I kept the style of just using the swing libraries in low-level way as opposed to using a gaming library like libgdx.

I'm not sure how far I go with this and currently you can not much besides walking and swimming around.
