This is a really good game, especially for a game made in a week. The music is solid, the art work is colorful, and for the most part the controls work pretty well.
There were a few times the controls got stuck, and wouldn't let me jump when I wanted it to. Felt randomized when that happened, but it did make some of the quick jumps difficult to nail. Also, I think little night would benefit from a larger attack radius. Instead of doing a jab, I think doing a swipe where it also hits enemies above would help in the game. That would make the difficulty feel just right.
While these issues got in the way a few times, it didn't happen a whole lot, and definitely didn't take away from how fun the game is. Nice work!
