The mechanic of this game is excavating blocks with the mouse, creating a path to the green block while avoiding red blocks, and then pressing R to let the robot character follow the path. If the robot hits a red block, he gets teleported to a random level and you lose some points. If instead he hits the green block, you go to a random level and gain some points. I'm rapidly updating this game so this mechanic might change slightly in future updates, though i want to make sure that anyone can play any version of the game.
