Were there ever violent Game Boy games?

[renegadechic]

"Fortress of Fear" made ME violent, I remember that I've never made it through the first (!) Level, what a crap game, luckily it was just borrowed.

Its weird but as a kid it didn't occur to me that games might be made badly or hard to play, i just got on with it and i think i either completed this or got close when i was surprisingly young i.e. 7 or 8. Of course now when i pick it up it is unplayable!
