Visuals:
1 ... simple camera main menu movement would made game look so much better (it gives motion)
2 ... elements in game fits together
3 ... main -> game transition: this looks like lerp rotation -> try different interpolations or pass <Unity custom Curve> to interpolate this.
..... reason is that currently it looks little wooden
4 ... outside the window -> dark or image in distance would fix problem of seeing only plane color
5 ... this dude in fog scared **** out of me -> would be funny if guy started running after me & if I get caugch -> game resets
Controls
1 ... responsive -> very good
Design
1 ... going in elevator & out then scene changes completely its looks strange but why this guy here on chair is not surprised his legs are in water in next moment?
2 ... me been able to interact with env like: kicking chairs, moving some small objects would give a lot of the weight (currently most of elements are static).
3 ... small scope, reusing scene with min difference -> very good
Sound
1 ... fits theme very well
