In episode 2-3 you have to go to Oolong's house and solve a long puzzle involving going through all the rooms and at the end, when you have solved the puzzle and pushed all the switches in the house, the main doors are opened and you enter the room to fight the boss (Oolong in armour) I lost almost immediately to the boss and found that when I died I started all the way at the beginning of the episode! Where are the save points in Ooolong's house?
