Green Top

Green Top is a 2D puzzle platformer metroidvania. The player takes on the role of a copper robot who wakes up after being infected by Green (copper-eating grass) and has to find out who he is and what happened to the robot world, now also infected by Green, to do whatever he can with the tools at his disposal. He is able to locate where the Green grows and can attach to himself different arms with various effects from scrapped robots that he may find along his journey. The environment tells the story of what happened and how it all came to be, and the player can find clues and secrets that reveal fragments of this lore.

The game's main hook is using climbable surface as an expendable resource: the player robot can ride along grass walls and ceilings but the game's objective is to get rid of it, so the first two arms provided to the player are a water-gun that spreads the Green to copper blocks and pushes objects and a flamethrower that burns the Green and propels the player making them able to reach higher places. The player finds many more arms along their journey, all with their properties, primary use, secondary use, some special uses when mixed with certain other arms, and other secret uses.
