Is it just me or does the drums of the music fit the dynamic camera perfectly in style? :D Nice rolling and release mechanic and I appreciate your effort to put in some decoration like flowers and stones. If expanded, maybe add a score system or flashing texts for extra high jumps. Something to reward the player for not just keeping the mouse button/space down but actually aim for perfect timing in releasing.
PS: Of course I would like your rating on my game as well ;) https://itch.io/jam/gmtk-2019/rate/460633
