This Is The Unused Super Mario Bros 2 Prototype Underground Theme And It was Dumb Of Them To Leave It Out Of The Final Game Because It's Pretty Gud. There is Also A Sega Genesis Remix. Press 1 For Original, And 2 For Sega Genesis. I Might Make A Remix Of This.
The Background I'm Walking In Is My Own Take On The Underground Sections Of An Unused Sonic CD Stage Fans Call "Relic Ruins" For The Fact That There is Unused Concept Art Depicting A Ruins-Like Stage. And There Are Also Unused Enemies And Even A Boss From That Stage That Never Got Past Sprite Creation. The Time The BG Is Set In Is The Bad Future Variation. The Sega Genesis Remix Actually Sounds Like Some Sort Of Bad Future.
