What a beautiful game. The music was very pretty and the pixel art was extraordinary. I loved the background most of all.
When I learned about the run and jump higher option, curiosity got the best of me and I jumped over the barrier on the rightmost edge of the screen (where you first collect all the flowers). I dropped off the face of the earth (but I got to see some of the beautiful pixel art down below that I wouldn't have gotten to see otherwise) :). Nice work!
