The atmosphere is interesting and I really appreciated the lighting, simple but effective. The 15-minute timer, although in strong contrast with the feeling of disorientation, still pushes you to want to reach the end.
That said (SPOILER): the lack of clear visual references makes the maze very disorienting. It’s often unclear where to go or what the objective is. Enemies seem to respawn, so they don’t work well as landmarks, and when a door is unlocked the message doesn’t help in understanding where it is, leading more to wandering aimlessly than to facing a real challenge.
