So I liked the game, nothing satisfied quite like a 2D platformer, and your level designs are good! You used the 1-bit theme of the jam to come up with some creative obstacles to overcome.
I don't like that there isn't a victory screen or indicator once you've beat the 5th level. It just looped back to the first level and it took me a moment to realize that I'd already beaten that. Anyways, good game and good luck on your future projects!
