Nice concept! The art is super pretty and the music very relaxing.
Although waiting for the seasons to loop is super clever, I think I agree with some other comments about the lack of "things to do" while you wait. It can sometimes feel like an eternity if you miss a jump. Perhaps you can test a button that lets you speed forward to the next season or something like that, with a cooldown or limitation like "touch the ground first" (similar to celeste's air dash).
That said, the idea is neat and I believe you have something going on here - I have a feeling there's a world in which you can refine this a bit more, add some more strategy and end up as a real storefront game, push for it!
