Gave it a go, but it's not really my thing so I only played through the first ten levels.
My only real feedback is that the level end screen takes way too long to sum up your collected flowers.
I don't know about getting hurt making your ranking worse - on the one hand it's kinda boring that there's no fail state, but on the other, your control over your trajectory is kinda limited and I could see it getting frustrating.
The bee's cute though, and the varying finish animations are a nice touch.
