Black Castle is a homebrew action-platformer for the Game Boy, developed by 7FH and released as a reproduction cartridge by FernanteCrafts.
Story: The times were dark and the kingdom was threatened by a black warlock. His evil magic brought disaster upon the land, but none of the king's knights found the courage to fight him. Just when everyone had given up hope, a young knight appeared. He set out for the sorcerer's black castle to save the kingdom from his tyranny.
Gameplay: Fight your way through four exciting levels, finding secret passages, hidden items, and enemies like skeletons, mummies and giant spiders along the way before facing the black warlock himself. The game is compatible with the original Game Boy, Super Game Boy and Game Boy Color, displaying in color on GBC hardware.
