This place definitely is not going to pass the OSHA inspections...
No but, great fun little game! I think the architectural design here is definitely the highlight, the environments felt somehow naturally man-made(?), like a real building instead of just game set piece but still uncanny in it's elements. And I am not saying that just because those types of stairs give me anxiety, just look at them they are going to fall down any minute, I don't even think they were attached to walls. But for real, small details and additions to give more space and depth to the building like the small windows to see and double doors, good stuff. I did find the walk a bit humorous though, but in that morbid humor way, which I feel was somewhat intended too. Good respect for the sound design too, it was simple but I do think you managed to nail it good enough that I felt the immersion kicking in just walking on the metal-grate bridges and watching down to the what I assume were pools of something very hot lol
Very nice, also huge probs for having Unreal game which didn't instantly set my GPU on fire :) That is rare I tell you. Great work.
