Wow the lighting and colors are fantastic. As soon as I entered I was very impressed with the visuals of the game and the subtle electric light buzz sound. Really cool.
I assume I have to find all the keys to escape through that door with the ramp but... after getting the blue key and the red key and two flashlights I passed the green key once, and then 10 minutes later I still couldn't find it. Gave up.
Could really use some 70's retro furniture sprinkled throughout the level, that would liven it up a bit, maybe a few special rooms with some story as to why you are in this procedural building. The keys could be placed on a nice table and look like fancy keys instead of just the blocky blue red and green. I'm sure you had plans for that kind of stuff, but 72 hours is short!
