I had a lot of fun figuring this one out. Think I died 3 or 4 times in the first 2 minutes to begin with, but it never felt unfair, I had always done something really stupid.
I really loved the variety in the rooms, all were implemented really well. The blue room genuinely scared the living daylights out of me the first time. I would have liked the yellow room to have reset after completion, but that's mostly me just being lazy and not wanting to retrace my steps.
The sound design is standout for me, it really adds to the effect hearing you-know-who stomping around. The grunts from the VA's are great too.
Thanks for this, had a blast.
