Really neat game! It was a bit difficult to figure out at first but once you get it it's got a lot of potential.
I especially like it for the one enemy that passively spawns attacks, which makes it actually challenging to die.
The art style is also very unique! I personally quite like it, but the blurriness makes it a bit inconvenient for a platformer. Still, it is very pretty and I think your limited use of color works well with the pixelated look!
