Honestly huge props to you for even committing to a fully 3D animated character for a jam like this. That I'm even able to give specific pointed feedback shows how far along you made it in such a short time! Hugely commendable.
I'm always happy to chat about this sorta thing - feel free to hit me up on Twitter, Bsky, or Discord if you ever want to talk shop on 3D platformer design/implementation!
