Thank you! Yes I was pushed for time, so a post jam update will be available soon with improved mechanics and the like.
Very good guess on Daz3D. It's actually another 3D modelling program called iClone, similar in all ways to Daz3D. The trick then was to make it 8 directional 2D to appear 3D in a game engine meant for 2D. The protagonist's sprite took me a full day's work alone but I think she was worth it ;)
