What kind of art-style are you thinking about? I usually default to pixel art for game jams because I can turn it out quicker and it's easier to keep it cohesive but this jam is a month long so it does leave more room for other 2D styles. I know some 3D modelling but I would have to re-learn rigging cos it's been ages since I've done it.  I'm also really hoping to do some design work though so if we team up I'd be looking to also do game design- I was thinking of trying to make a mini-rpg or horror game since there's more time for this one.
