Nice job for your first game jam! Kudos for going 3D - it is usually a bit harder to do.
The concept is very interesting and matches the theme. I'd say that UI isn't the prettiest but no one expects you to ship a fully polished game in a week. Also for future game jams it is a good idea to include a browser build on your itch.io page - it increases your reviews dramatically!
Narration is awesome, it is rare to see on game jams:) The whole project feels like prototype for a much bigger game which is nice.
Great work and keep up:D
