I didn't expect a platformer to come out of that prompt, but you managed to do it in your creative ways (if I were the one who got that prompt, I would be stuck with making a point-and-click game or a visual novel).
I managed to get to the part where the hole opens up but then find myself stuck lol. I saw from the comments that I need a pair of high bouncing shoes so I'm glad to know I actually missed things.
I also like the calming music and the boy (girl? genderless mushroom/fungi?) fishing on the crescent moon is a nice touch (which I think is a reference to Dreamworks).
Thank you making the game and I hope you'll keep up the good work.
