I thought this was a really nice game, and I love the paper visuals, that's always neat to see and it makes it stand out among other 3D and 2D games! The bullet-hell aspect was executed really well too with a few different bullet variations and patterns that are fun to dodge.
I think that this game's biggest flaw however is the lack of audio in a lot of places. I feel like some music could help, even if it was more laid back to fit the style of the game. And maybe some different variations for the drawing and erasing sound effects, as that can quickly get a little repetitive.
Other than the audio though I think this was a really great game & submission!
