Good game and amazing concept! I think introducing more kinds of moss blocks would enrich the game. Like a white moss that gives player a speed and jump boost.
Thank you! It's a cool idea. In a very early version of the game I had "timer moss" which would reset if you didn't moss an area fast enough. I removed it because it felt stressful and too against the feel of the game. Variations like this are still interesting to me though.
