Interesting game. As other comments have said, it's a bit rough that the game doesn't explain how to survive the monsters.
Also, were the similarities to Spooky's Jump Scare Mansion intentional? You've even got Specimen 7.
Originally, it was inspired by Spooky’s Jump Scare Mansion and this is also (kind of) the case with the big wall monster. It was both inspired by Spooky’s specimen 7 and a nightmare I had that I wrote down in a dream diary I have (which is also the inspiration for the monster that spawns in the pitch black darkness).
(it’s also because I couldn’t rig anything or model anything decent during the time I was working on this for college but let’s ignore that haha)
I will definitely add some hints that players can read on how to survive monsters (like another commenter suggested, notes in the environment). Thanks!
