The SG-1000 port exists already so it would be very straightforward (just adding 8K more to the ROM to store the new mazes and pattern styles).
I've just purchased a new Commodore 64 Ultimate (still waiting for it to be shipped) so porting Guzzler sounds like a good idea for my first project on such computer.
A C64-port of "Guzzler" would be very nice indeed. Many good new games have been released for the C64 in recent years, including some truly excellent new ports of Arcade classics like Donkey Kong, Galaxians, Burger Time, Berzerk, Galaga, Lock 'n Chase, Donkey Kong Jr., Pac-Man, etc. Guzzler isn't available on the C64 yet, would be fantastic, to have this classic available there as well.
