This is an amazing platformer, and the amount of content is incredible for a 48-hour jam! I especially like the art style, which is simple, but the subtle bloom effect makes everything look great. I would say, though, that it feels like I need three hands to play it. I would recommend maybe only control with WASD but you can change which character you play as by clicking them. Just an idea.
I like making platformers as well, so you might like my games. If you have time, check them out!
