Played through both this port and the Amiga one. Honestly I liked the PCE version better.
There were still many moments rage found in either version. I think I preffer Cacoma Knight, honestly. It looks a bit better in my opinion and is alot easier.
I haven't played Cacoma Knight, but it looks interesting and I've just put it on my list of games to play
at some point in the future (before I die).
I spent a ridiculous amount of time playing the orignal Qix (arcade and ports), so Volfied on PCE was a nice upgrade for me.
I will admit that the "naughty" version of Qix/Volfied (Gals Panic) is actually decent. No, I did not play the game for the digitized boobs. The overall presentation and mood of the game is compelling and endearing on its own--they did not need to use boobs. It would have been nice if the developers explored a creative, non-boob angle to the game.
I'm totally serious!
Anyway...
