Play the original Black Castle Game Boy homebrew offline, plus a short local castle challenge. Black Castle brings User0x7f's original Game Boy action platformer to a focused Chrome toolbar popup. Enter a fortress ruled by a black warlock. Fight through four complete levels, uncover secret passages and hidden items, learn the strengths of four weapons, and defeat the boss waiting at the end of each stage. Original mode is selected by default and preserves the existing Game Boy game's graphics, levels, enemies, weapons, secrets, boss fights, controls, and presentation. Castle Run is a separate secondary HTML5 challenge for a shorter practice session.
