The environments are good and the setup - but, the 2nd portion of the game isn't as 'fun'? I couldn't find the 'key' to escape/to the door next to the elevator, the doors kept breaking/letting me walk through them sometimes - eventually the Locked door just opened itself while still telling me it was locked and, upon trying to enter, fell through into the void through the floor.
I checked the closet, the room I got the flashlight in, the room you start in after the 'explosion' and the cafeteria-looking area and found/saw no key or anything shiny or anything relevant, played for 30-40 minutes and stopped after falling into the void. The doors are an absolute PAIN in the ass to try to open because of hit fickle and OCD on where they want you to be or stand before it acknowledges you 'hit E' (maybe 50 times). The doors can Shove you around and just are a nightmare to interact with.
Last feedback, the game lacks ambience while that monster/zombie thing was chasing me forever.
I can see potential but, mostly in the first half of the game with how the environments looked in attention to detail, 'imo'. Looping hallways in the 2nd portion, I wouldn't say I got lost, but, I used the flashlight on all the goop on the floor until there was no 'goop' either, still couldn't find a way to progress, unfortunately.
