I love a concept where you're just growing things and not fighting. Really neat to take and idea like fighting a dragon and make it about flowers. The flowers and the girl also look really cute!
There were a few gameplay issues I had. You had to stand next to the flowers in just the right space to water them or climb them. It's also not possible to get all of the music notes if you get the one near the cave since you can't climb back up. I had to restart to collect all of them.
I had a fun time exploring and and seeing how high I could go. Keep up the good work!
