Nice experience, with a vampiric backrooms feel =) I liked the lighting and the confusing looping architecture. I found the key in the hidden room but couldn’t find the lock for it, I’ll keep trying for a bit.
Thanks for the feedback! I was primarily inspired by the "Rooms" mode in Roblox and the game "Spooky's Jump Scare Mansion." In other words, you don't need to search for a specific spot to use a key in this game.
