[TAS] Wii World of Goo by STBM in 31:

This is a tool-assisted speedrun. For more information, see World of Goo is a physics-based puzzle game for the Wii. You create structures out of goo and usher around goo balls with them. The gameplay can be pretty interesting, with quite a few different kinds of goo to play with and some interesting puzzle physics to go with it. First time author STBM uses careful planning and some interesting glitches to complete levels in the blink of an eye. See the author’s notes
