Damn, this deserves the amount of reviews it got. The character design is downright impressive, the art palette awfully reminds of Hazbin's Hotel (even the idea is kinda close!)- Really great, fluid movement, too. The only thing that can be said about, and that other people on itch complained about, is the controls. Why use k and j? These are really uncommon. Couldn't you used w or space for jump and z or x for the long jump? these are more comfortable buttons for players. One thing I also noticed is that this was created solo, which is very, very, very impressive. Numbers:
Art: 9/10
Music: 8/10
Implementation of mechanics: 9.5/10
Theme: 8.5/10
Honestly, one of the best games in the jam. Amazing work! Keep it up.
