Congratulations on your submission!
I'd like to preface my comment with the game runs fairly slow on my computer, even with an updated driver. I guess that's just the nature of things since I'm on an old Asus ROG from 2015.
I tried playing for a while, but I got stuck in the first area you are able to enter after getting the first gem. There seems to be lava or some sort of hazard, and I managed to get two gems, one over the first hazard, and then the second at the bottom of the drop. However, I couldn't find any apparent way back up. So, the game basically just soft locks on me there.
One piece of feedback I'd give is that the rotation of the camera seems very slow (a different slowness compared to the game running slow), so it's hard to gauge where one is in relation to the game area. I'd love it if I could more quickly move the camera to inspect my surroundings. Also, the auto-save special effects can be distracting and caused me to unwittingly move into a hazard and die several times since I couldn't see where I was going. I will say that the effects may just be problematic because of the game running slowly on my PC.
Other than that, I'm still curious about this game and hope that some time I can jump back in. Great job on finishing it for the bootcamp, especially with doing your own 3D models!
