Occasionally when you switch characters the one you switch from will standing in a slightly different place than you left them. The glitch seems to undo the last move you had them make. This is troublesome on the pressure plate puzzles. Other than that, it's pretty good.
Cool game ! The only thing I didn't really like are the controls. I mean, it's sometimes hard to control the character, it get stuck. Everything else was perfect for me !
Great game!Love it!
