Very refined concept. I found many levels frustrating though. On one of the scrolling levels I couldn't see the spikes down where I have to move to.
Very nice music, visuals and general aesthetic.
The jump sounds blends a bit too much with music for me. I think it makes for reduced feedback.
The fact that you keep the double jumps death is easy to miss. (I know the flower is supposed to lead the player to that conclusion, but if the player tries to jump when catching it, he'll miss it).
I liked the credits screen.
