Hey hey, played this and it's awesome! A strong core mechanic with excellent (and cute) execution. One bug encountered was that the underwater flower's and one others petals started flying all around the screen back and forth haha. One suggestion I'd liked is that you could also cut the wine by pressing jump. This would make sense as usually this also lifts you up, giving it similar meaning to using jump button. Of course this should only work when in air when you can't jump either way.
There was also at least one case where you couldn't go back to the previous level (since the next one was below), so accidentally went to the level before getting the flower. But overall, great job.
