The art is awesome, and the concept sounds really cool.
Just my preference, but I would love if the "growing" aspect was kept central to the game. Maybe it could also be used to power-up/evolve your creatures with items you collect in the world.
Yeah the player feedback on failure is definitely bad, I think adding a fall animation or like you said just preventing the move would have been better.
That may not have been a bug you encountered, but the "stick" mechanic I added to the rose. Unfortunately the only way you can tell you're stuck is by the sound, which is definitely not ideal.
