Pretty cool, took me a while to finish this since the walking speed is reduced considerably, but pretty okay.
The starting area can get a bit dull though, walking around the same room copy pasted 64 times can kinda kill the moody atmosphere, especially with the looping emergency noise.
I think i even missed the shotgun the first time since i don't want to bother searching the other rooms and got stuck facing the first corrupted.
Could have had the flashlight spotlight larger, reminds me of the days playing AoM with that small thing.
Also, i've found this.
EDIT :
Also found the little secret in the acid room, got me into reading the ol' wiki for new entries again.
