Twisty's Asylum Escapades

Twisty's Asylum Escapades is a dark, 3D, single player, action-adventure video game and is the premier gaming project by the masterminds at Twisted Jenius.

You play as Twisty; the evil, disembodied floating brain with a mouth full of razor sharp teeth, as he makes his way through this bizarre mental facility, fighting enemies and solving puzzles in order to secure his own "early release" from the asylum.
