Doing a 3D game for your first game jam is a real challenge (this is my 5th game jam, i studied 3 years in 3D school and I only made 2D games so far hahaha).
I think you made something pretty solid and original. There is a few things that makes it hard to enjoy the game (collisions on every small items, hard to tell how to pick stuff, UI broken because of web export (not really your fault)) but I think you should still be really proud of your work !
Congrats on your first jam !!!
