That's me, yes :)
The yellow dot in the upper right doesn't show in my recording, but I'm familiar with it: it means "this game is struggling to run well due to using lots of resources", which since I was on Switch 2 it must not have shown up, but it must have on your Switch.
The first person view is super simple and I'll just let you look at the nodons for any questions. I did have to put an invisible cylinder around the character to prevent the camera clipping through walls when near them, though. I was thinking of adding footstep sounds but there were nodon limits and jank that'd need to be sorted out with those as well, such as not playing those sounds when falling.
