All around good game. The controls felt good, the soundtrack was fitting, the sound effects were on-point.
The fact it took so long to break things open added to the mood of the game.
The one time one of the monsters pursued me, I hid in a locker and they just waited outside. I don't know if they don't have a wander mode for idling or if they actually have object permanence, but it mechanically made the lockers unhelpful.
