Woah this game is really good, I really like the simple but still good looking graphics in combination with the music <3 Only thing I'd change is maybe the way jumping works? Imo in order to reach max height you have to hold the button a liitttle bit too long which felt a bit awkward at times, also a reset button would be nice in case you screwed up hahah, I kept re-entering some levels hoping it would reset the level.
But this is probably one of the best games I've played in this game jam, great job <3
