Arrow keys to navigate through the bosses from my original open-world scrolling RPG, even the ones that weren't added. This is basically all the boss-related lore of Phantasie World, and I mean the world, not the game. All these bosses canonically exist in the Phantasie universe, but I haven't added them yet. They're all pixel-y because they were made in the 16-bit-ish game that Phantasie world is a sequel to.
