The art and music are on point. The dithering is a style I want to find a way to incorporate into game shaders for 3d engines. I love the game as well, but the music and art is what makes me want to keep playing the most.
Shaders are a bit of a gap in my knowledge - I really threw the transition shaders together by looking at youtube tutorials and basing it off a gameboy shader I used in my other game 'Super Squeakeasy'!
