== Perfrak - 'adult' version == 

 Pretty sure I didn't make this up, but I recall an 'adult' version of the game, where Trogg used his man member instead of a yoyo, the monsters were more vagina-like, and he would shout 'Fuck!' on dying instead of Frak!  I played it on a BBC Master, pretty sure it was called PerFrak.  Identical gameplay, so likely a humorous rip-off with some graphical resources changed.  Only played it once or twice as the game didn't really appeal to me in either form (I'm a Chuckie Egg man). 

 Anyone any references/memories?  Am I the only one?  Am I going nuts and making this up??  Posting here for completeness just in case anyone else has memories, or better still find the binaries!
