First and foremost - I really like how the controls feel. While it is super simple, the game demands very precise movements because of some of the boss patterns, so the controls work out very nicely, which is awesome. The art style is excellent, and I especially like the worm boss (which reminds me of the Destroyer from Terraria); great use of emissive details to bring a very pleasing aesthetic to a minimal environment. Great stuff on every front.
