There isn’t really anything spectacular about the graphics of Twinsanity. They don’t stand out as being revolutionary, but there aren’t any major flaws in the looks department either. Crash’s graphics find themselves on the upper end of the "par for the course" range that has been part of the 3D-Platformer genre for a few years now.
The music does a good job of adding to the slapstick feel of the entire game. To add to the less-than-serious feel even more, you are treated to a multitude of shouts, hits and bangs as Crash and Cortex fight their way through the game, which seem to come straight out of a Warner Brothers cartoon.
