Pixling World has gone through many phases, from the initial neural network playground (that me and MPJ from FunFunFunction chatted about over a year ago), to an ecosystem/evolution sandbox simulator and now in its final version, a "bioengineering battleground". In this latest version of Pixling World, you bioengineer the bodies of your Pixlings, and then use evolution and breeding to optimize their behaviors. You then battle your team of Pixlings against other players teams, to reach the global #1 spot! Since this concept is so different from the original concept, we've decided to change the name to "Dr. Derk's Mutant Battlegrounds". Dr. Derk's full name is Cork Derk, descendant of Cark Derwin, the great biologist that invented the mutant battlegrounds!
