Heyo~
I had a lot of fun playing this game! I thought the concept of fighting your sleep paralysis demon was really cool.
One suggestion I have would be to really lean into the sleep paralysis monster theme, when I think about the theme I'm imagining more shadowy, almost human kind of beings. I thought the spears were a lot of fun but I didn't really understand how they fit into the theme of a sleep paralysis monster.
Like I said, I thought that the combat and the mechanics were really fun. I think you made a really cool game, great job!
