Octopus is a hack of “Super Mario World”.
Mario returns from the record store with his latest haul and puts on his used copy of Octopus by Gentle Giant. The music takes him on a journey.
8 levels with steadily increasing difficulty, inspired by the 8 songs from the album, each focusing on a different mechanic. Starts off easy, but ramps up in difficulty. No shell jumps or super advanced tech, and trolls are contained to one short level.
