This is a port to the Commodore 64 from the arcade original. I have played both and believe that the C64 version is clearly superior which is quite impressive for a home computer of that generation.
The gameplay is so simple, there’s no powerups, no collecting of any kind in fact, just a fixed number of mazes and at most 6 enemies on the screen at once, but if I had to guess I would say this game is the one that I have played more than any other in my lifetime, it is just that good.
Getting the target score single player was quite a challenge, I would say 95% of the time I play this game in co-op mode rather than single player. Having that second player makes getting higher scores that much easier, as you are never without a Double Score Dungeon bonus.
