Moss Moss is a non-combat platformer by Noel Cody where you play as a little moss ball trying to fill the world with moss. Sometimes described as a metroidvania or "microvania" (but with only one post-game ability upgrade), the game features an 8x4 interconnected map, with the goal being to cover all the unmossed surfaces. Mossing up each screen spawns a leaf orb, grabbing which adds to the 32-step leaf path that lets you reach the top screen and finish the game. There are also 15 spirits that can be collected along the way.
potaterhands achieves the Fully Mossed ending by covering every surface with moss and collecting every spirit in record time.
