Nice work on this one! Short, spooky, and pretty fun to go through.
Only feedback I have: It feels like once the monster sees you, it's basically impossible to escape unless you bug out the AI. Not a huge problem since Retry keeps your progress, but it did disincentivize running.
I'd also really like a toggle to turn off the PSX filter; personal taste but I feel like it mostly makes games hard to look at and play. That's just my own taste though, didn't really affect my overall enjoyment of the game.
Keep up the great work and can't wait to see what you make next!
