It's the game Crinsom eve2. Where Kally must fight her way through a twisted insane asylum to save Byron who's been wrongfully committed. Along the way she's acompanied by Fred, who Kally can use as a weapon. But watch his insane-o-meter, if it maxes out Fred snaps and becomes an all powerful uber-boss that simply cannot be defeated. Wich is where the chocolate come in. You can either use it to raise Kally's life bar or use it as a peace offering to bring down Freds insane-o-meter.
