Amazing game. Aside from the whole "make a platformer but easy mode" thing I found this really fun to mess around with. Customizing my preferred controls was fun, especially with juice, but cranking everything to the maximum or minimum is fun too. And playing through the whole course as the platformer gods themselves is great.
Thing I thought of while playing as Madeline: a "one level, multiple characters" game would fit really well in a jam, and even one of your older jams (2019 I believe) had a amazing winner with a similar concept. Maybe "one level" could be your next jam theme! I know I would have fun playing a bunch of games in that style. I'm sure you'll think of something better in time lol but it would be cool
