Nice sprites and really great level design (so far). The MNK design sheet is also a sweet little addition to the game world.
Having already seen most of the graphics at the Discord channel, the promo manual was one the biggest new things of the relase. You clearly put a lot of time and thought into it and it pays off, as I can imagine the game pretty well. If you should ever turn this into an actual game, I'd love to play it!
