Pretty good for a second effort! I didn't notice any physics weirdness, just a few cases of the camera clipping inside trees and such. I liked the mouse animation as well. Cute to see it jump. It was engaging enough to play through several times.
I initially thought I was supposed to eat all the cheese but I soon figured out the cheese only helps you live out the nightmare of rat-eating-mouse rodent cannibalism! :)
The native builds worked fine, and better than the browser version for me.
BTW you might want to mention the browser version requires WebGPU (thus special setup for Linux folks).
