I can easily say this is one of my favorite game jam games ever. The music is perfectly loopable, the art/layout is good, and the level design is solid. I love Bennett Foddy-esque games and have completed both New Babe and New Babe+ of Jump King (New Babe+ is no joke!)
I finished this game and want to call out one spot that I believe does not follow the formula that makes these games great: https://i.imgur.com/MSWb4e1.png
This bucket is stationary the first time you get here, so it isn't a very hard jump. But after you fall and come back to it, the bucket is continuously moving and the cycle doesn't exactly line up with the cycle of the platform you are jumping from. This makes the jump feel random and unfair. I fell on this 6 or 7 times in a row and almost gave up because of the inconsistent timing.
Two ideas for fixes: Make the bucket stop whenever it is at the right side or make the platform and the bucket movement on a consistent cadence so the player has a similar setup every time they try the jump.
Overall, amazing job!
