Really good fangame, I love the bit of lore scattered everywhere and the posters (the stitched lips are my favorite). The addition of AI generated pictures to represent the concept arts of the Greeter is a good thing, it's kinda scary when you see it after a corner. The horror parts are really well made too, caught me off guard.
My only criticism is the first part of the game have really bland textures for the walls and floor, except for the office room with white and purple tiles as seen in the screenshot, but it get better with the 2nd part.
Looking forward for your futur games, it's a really good start.
Ps: thanks for putting stripped steps before the holes in the dark area, it helps a lot !
