About art, if there was some gradient (for both flashlight circle and for things appearing from far), it would be more pleasing to the eye (in my opinion of course!). Regarding controls, I had to scale down my mouse sensitivity a lot not to flip my head around each time I moved my mouse up/down :P And some ability to run e.g. using shift would be nice. Otherwise it was fun, didn't get too far during my 2 tries, unless there is no real endgame condition for winning (I think I "fixed" all the panels with red lights on the ground floor and one on the first floor, or maybe I missed some). Could be an interesting horror game if developed further :)
