Thank you for the feedback! I used my own custom engine for this, which is why pretty much all of my games use the same art style hahaha.
As for leaves getting stuck in rocks…that should not be the case: I explicitly check that there isn’t a rock underneath before a leaf falls all the way to the ground, but it’s possible that there is still a bug somewhere, so thanks for pointing it out. Leaves ending up off-screen is intentional, but I should probably indicate more clearly where the edge of the screen is (with a fence or something), so the player can plan ahead better. I also need to playtest more to optimize things like starting height and falling rate, since I just picked the first numbers which came into my head.
