The PC version I could never get past the cook she always turned around to fast, which bugged me for a while cause I couldn't even beat it. Well the problem is a fast PC will cause the game to skip frames and make the cook turn around. The solution, I just beat the game on PC today, is to get a DosBOX Emulator it perfectly emulates DOS, so when you get to the part where the cook turns around, when you distract her she will face the wall in front of her til you do what you have to do.Get a DosBox Emulator and run the game on it and you'll finally beat the game without the cook turning around.
On another note Dymanix was going to make a sequel where Willy would be a teenager but it got canceled.
