I can't figure it out. The manual says hold "triangle" to bring up a character select screen, but when I press do that, nothing happens. Do I have to unlock the ability to change characters or something? I've complete level 3.
If I remember from the PC demo, you press and hold down the button, presumably Triangle in your case on the PS3 pad, and a radial wheel should pop up allowing you to select the character with the analogue stick. I'm shocked that the game doesn't explain though this given that it is primarily aimed at younger gamers!
