This is an animation of the boss battle. Sonic will be able to run on the foreground behind the cannons. I experimented with a boss health bar, and I think it works really well. To beat the boss, go to one of the cannons' lighters, and wait for a light beam to spawn. You'll have to move once they do, as they can do lots of damage to Sonic. For now, Sonic is replaced by the mouse until this is added into the game.
