I'm a 3D artist, I can lend 2-3 hrs a day making the assets. I can also lend suggestions for adhering to the theme, I'm pretty good at finding solutions to problems from a game design perspective, even if I am not the best programmer to implement them.
Edit: I can also do a little foley sfx too, but I'm bad at making music (quickly) so don't count on me for that xD
