I discovered this game entirely by chance as a rental in Blockbuster video when I was around 13. It transformed the SNES into a fantasy evolution simulator with hints at a deeper, darker story despite lighter humor in the game as well. There are a surprising number of secrets to uncover - how to become a bird, how to evolve into a human, etc. There's even a level where it's possible to become a mermaid if you find the correct path. This game has more depth than an early 90s sidescroller has a right to. There's nothing else like it as far as I know. A great relic of wild 16 bit era creativity.
