I played the two first games and liked them but this part is not good at all. Graphics is OK but the game was probably made for a console and ported over to the PC. You play the game using two sets of buttons from they keyboard containing four keys each. It is NOT possible to use the mouse. To make things even worse somebody decided to add action sequencies to the game. These can be very/extremely difficult. I suck at playing platform games and anything else that requires good hand/eye coordination making this game (an adventure game....) impossible to finish.
I am really sorry to say that my firm recommendation is to avoid this game.
