The C64 Version was released 2 years after the original. Due to the limited hardware, Flair Software was forced to compromise in the form of removing one of the three film studios (the den of the monster insects) which is why the procedure of solution is slighty different in the C64 Version. Nevertheless, no violence has been censored. But there also two minor differences that are rather strange: a censored pin-up calendar and a changed license plate.
