The game is pretty raw as of right now but overall... it's alright. Sensitivity is too low imo and it's not quite clear what to do after getting the key. The ambient stops after a while, the game is a tad bit too silent and there being too much rooms that lead nowhere. Other than that, I can see it being an interesting project!
One thing I would like to know, though, why is there a putin graffiti? It just looks so out of place.
