My ludum dare 38 entry is a game called Mini-Shaders. A programming puzzle which borrows from the idea of shader programming.
This is my first time making a puzzle game, never mind a programming puzzle game. It was a pretty fun experience, although I realised towards the end that I was missing a couple of commands to make the patterns truly interesting (such as abs). There were also reports of some bugs here and there, which I guess is somewhat to be expected as I was really pushed for time.
This was also my first compo entry, which means that all the art (which was really just a bordered square made in inkscape), sound, and programming had to be done alone and within 48 hours.
The game can be found here.
