Black sun

A blue stick figure runs toward a grey stick figure holding a shovel, then punches it, sending the grey figure flying backward into the water. The blue figure then runs across a collapsing bridge, causing the grey figure to fall through a trapdoor, and finally walks away as the grey figure lands on a seesaw. The scene takes place on a cracked, floating platform above water, with a large pillar and distant land visible in the background.
