Once the title screen is gone, click on buttons to change your boss's appearance and functionality. The triangles are page switchers. There are multiple pages of appearance, functionality, and more. Made servants do more things. Also added clouds. CLOUDS!
I came up with this idea when I started getting hyped up about Terraria's bosses, and wished they had a custom boss maker mode, but they didn't. So now I am making my own. Credit to the Scratch team! Credit to PopCap, I took some the sounds from Insane Aquarium. Credit to the makers of Terraria for some of the ideas.
