That was a very cool platformer! The puzzles, art, and music were very soothing and fit together really well. The animations were very slick. My favorite mechanic was the puddle teleporter, and I also really liked the blowing leaves scene transition. All three character states were very clear and distinct too, and were a very creative take on the theme.
I did get a little confused in the early levels by the flowers/ice mechanic. I thought they were all one way changes at first, and didn't really understand it was a "hot/cold" state transition based on your current state until "Crossroads".
I also didn't learn how to reset the level by hitting [R] until after I had already broken the game by going backwards during that level and refreshing the whole page :*(
Really great job!
