Play Mario Legends I - The Spectral Room Online

Mario Legends I: The Spectral Room came out for the Super Nintendo Entertainment System, though I don't recall who made it. It fits right in with that era of platformers that tried to do something a little different with familiar characters.

You control Mario through a series of single-screen puzzle rooms, each one a self-contained challenge. The main goal is simply to reach the exit door in every room, but getting there means navigating platforms that fade in and out on strict timers. You have to watch their cycles, memorize patterns, and make precise jumps without hesitation. The pacing is deliberate, almost tense, because one mistimed leap sends you back to the start of the room. It feels like solving a spatial riddle with every new screen.
