Efencea is a two-player competitive defense game. Players create waves to assault their opponents and build defenses to ward off their opponent's invading forces. Efencea is written in DM, the programming language of BYOND (Build Your Own Net Dream). Production began in early December of 2008. The goal? To produce a fun defense game in a very short time. We may not have met our goal of 7 days, or even 14, but it has definitely been an exciting project.
