No matter how many times I walked through that room, I always expected that bed to be empty the next time I entered. The fact that you can create that dread/anticipation without feeling obligated to deliver cheap scares "just because" is why this game deserves a 5/5.
This is what escape games should be. Multiple rooms, good graphics, a decent story, puzzles that make sense (I seriously hate escape games where you need to do a sudoku puzzle to open a dresser or something) and it didn't require mindless clicking to find any hotspots. Turning the valves was a bit of a pain, but otherwise 5/5
