regular zombo fighting gaem

solo developed game. very buggy and probably my only purposely public game (THIS IS CD0 aka CORE DEFENSE 0) (..or, CD before it was CD.) (This game is . .SO BAD . !!) (It eventually led to a dev game, known as "gunship test" to test a new super unit for RZFG, which became CD1, starting the CD series.) (.. SO Play CD3 not this slop :sob:) (It helped teach me how to code, i guess .. ?? i was like a lil gaggling baby back then tho its so broken and unoptimized like cd1 is)
