Oh this was a genuine treat to play! I loved every single "level" and was for real spooked when I got chased! Throwing wrenches is such a fun way to attack!
I was slightly disappointed with the story - wish there was some kind of twist, or at least an ending after the boss, instead of straight to credits.
Right at the Inlet part, after I was returning from inlet A, I thought "now would be a good time to introduce the enemies" as I almost ran into the translucent bastard!
The puzzles are incredibly solid and show an appreciation and love for the genre, the boss was simple, yet tense, and the chase in the third area gave me the heebie jeebies for real.
