Description:
Where SMB Attacks (10 Years of YouTube Release)
Version 1.1

This game was made in 2010, but was never recovered. Spencer Everly has thought hope for remaking the levels and the game, so he then decided to remaster the game, with brand new levels to spice up the randomness! Hope you enjoy this game!

You'll need SMBX2 to make this game work. Visit http://codehaus.wohlsoft.ru/ to download the engine.

Game Description
