The Wizard of Oz is a licensed platforming game for the SNES that was developed by Manley & Associates and published by the SETA Corporation. It is infamous for its very poor game design and glitchy platforming. Nearly all the characters have ineffective attacks except the Tin Man, who trades his ability to jump for effective attacks, and there's incredibly poor collision detection all-around. Enemy attacks can hit you even when it looks like they shouldn't and you can fall through platforms even when it looks like you clearly landed on them. And to top it off, there are moments where items have to be collected to progress, which the game often doesn't tell you until it's too late.
In this run, moon_dancer powers through the frustratingly strange world of Oz and exploits the game's poor platform detection to skip parts of certain levels and return back home to Kansas as fast as possible.
