Great creepy setting and story hook. Voice acting was a real nice touch too. Had some nice jump scare moments in there, and the health bar, while not that important, at least made it feel like there were real repercussions to being bad at dodging knives. The creature was sufficiently creepy, though sometimes it would linger in sight, which took away a tiny bit of the terror factor. I completed the game, but in a panic I ran to the final room and missed important dialog. Might be nice to keep terrified players from missing that stuff by default.
Overall I had a great time with this game, and I did scream a couple times.
