I'm in for LD41!
I don't have a lot of free time this weekend, but I'd like to put something together in a few hours (a Micro-LD if you will!) using my Java game framework Katsu: https://github.com/berkano/katsu (based on LibGDX). Other tools typically used: Tiled, Photoshop, Ableton, OpenMPT, Audacity. Have fun everyone!
