Mino collects gold, but will be hindered by rock guardians. They will be constantly walking around the place and if they detect Mino, they will chase him to thwart their goal.
Mino will destroy cubes of earth to form a path towards the golden rocks. Every time it destroys a cube, it consumes its energy, which has a limit of 5 units.
Mino has the option to improve his activity by capturing small rocks that allow him to partially recover his energy or become invisible to walls and guardians.
