I really liked the mechanics and style.
Would enjoy having the Doors being drawn out more or otherwisely shown as "place to go to", but that might be because I get myself lost alot in general in First person games.
I already told you about the Escape Key in Discord, would love to also be able to adjust the mouse sensitivity, but these are all little things of course. The game itself is already amazingly good for this short time period, keep it up <3
