I like the visuals of the game. It looks like you've put a lot of work into them. The theme is mostly in the story, not much gameplay wise. There is no sound in the game (which I get, my game had barely any sound too) so there is probably some opportunity for atmosphere lost. Your button raycasts don't work as they should, probably a scaling issue. Look into using anchors more. Wall colliders are off too - it is not intuitive entering the door.
