Just curious as to why this game has a Commodore 64 tag if it isn't a Commodore 64 game?
It's supposed to be in Commodore 64 style, even if it's not actually a C64 game. (I might be playing a bit fast-and-loose with system limitations like audio channels and max number of sprites per scanline, I'm not enough of a hardcore retrocomputing enthusiast to bother replicating flaws accurately...)
