Good concept, I think there's more to explore with this in the future. I really like the art style and atmosphere. Feels very Hollow Knighty.
It took me a bit to understand how to control the bat. I like the puzzles although I couldn't solve the one with the bug smashing through the walls. I can't get the demon back in time before the dookie smell (lmao) kills me.
Great job, especially in 48 hours! Would love to see a follow up on this.
