This is an interesting game. The controls feel a bit floaty, kind of like you are sliding on ice. The music getting louder as you get closer you are to granny is a nice touch, and the first time I got jump scared it definitely made me jump.
I did notice a couple of spots where the seams in the walls let the skybox peek through, but otherwise the atmosphere is great, and the game is definitely spooky.
I would love if you could give feedback on my game: Project Helix as well!
I'll be honest: games usually only go viral when they have a lot of polish, time, and advertising or visibility behind them. It's really hard to compete with that as a solo dev in a jam. But if you keep improving it, add some polish, and maybe build on the idea after the jam, you could definitely get some small streamers or Youtubers interested and watching people play a game you made and seeing their reactions is absolutely priceless.
