"Zuma-style"
Well, that definitely looks straight up like Zuma but for Commodore 64; still looks pretty great though for what I would have expected for anything C64 related.

Also don't forget to give a shoutout to the real origins of Zuma, the people at Mitchell and their Puzzloop/Magnetica games (and yes, they did make those way before Zuma and even tried suing PopCap for taking their idea, but that didn't go anywhere). I know of them because of the DS Magnetica game which had pretty nice design and music in it :)
