Though sadly, it had a cliffhanger ending and never saw a sequel and richly deserved one, this is a truly great marker in gaming history. I played it initially on the Amiga, SNES, and Genesis, then later on the PC. I must have played the "spiritual" sequel, Flashback a dozen times across console and PC platforms as well. Called Out of the World in the states, this was one of the first puzzle-action side-scrollers, but also one of the first that told a mature story where you felt invested in the main characters. It was intense, poignant, and intelligent. Totally worth re-experiencing, or experiencing for the first time.
