Nice entry! I love the diagetic menu with the levers is fun, though it could be more introduce if they're doors or something?
Something I noticed whole playing is that the player will 'hop' a bit when walking downhill. If you project the input direction onto the surface normal the character will stay stick to the surface. Check out Vector3.ProjectOnPlane for more information.
Also, playing without maximizing the window causes the view to drift slightly. I think this only happens at certain screen resolutions, so just messing with the in the itch page settings may fix it?
