Wow, what a game! So much to love about this: 

1.  The pacing was spot on. The way the game ramps up as you progress really makes it more intense, especially with that last phase and the "rage" type red overlay.
2. The limited information the player has adds to the atmosphere
3. Great sound effects and cues for events like when the killer enters the same room as you
4. I enjoyed the safe mechanics, as storing the combo in your head and finding the time to type it in kept it white knuckled.

My only gripes with the game were that Q was an awkward key to map to lock. I would've preferred something I could reach with my other hand. Second, the doors that were sideways (ie you could only see a few pixels off were sometimes difficult to see so the art could do with some better visual cues.

Congrats to the team, I enjoyed every second of this!
