Gemini Canyon is the seventh level in Adventurer's Domain. A level from the shoot-em-up game Gemini Wings, it has been modified to work as a platforming level. It begins high in the sky as the player works their way across clouds before dropping to the titular canyon and making their way across and down there, eventually hitting the water. From there, an auto-scrolling section leads the player back up the canyon in front of a waterfall, leading to the end of the level. As it is modeled after a shooter game, it has a lot of enemies, many of which fly.
