The 1994 sequel to StarTropics, Zoda’s Revenge again features the red-haired hero, Mike Jones, only this time he’s on a time-travelling adventure searching to find a series of puzzles shapes called “Tetrads”.
These Tetrads are actually a nod to Tetris, and in the Virtual Console re-release of StarTropics II their names have been changed to “Blocks”, probably to avoid any legal problems. But anyway, I digress…
