The layout made it look like it was a game at first. I guess it just seems like evolution is something better expressed there. I still love this. I was very impressed by how good the animation was. You do fantastic transitional scenes. The music was really good too.
This isn't how evolution works. Well, the part with the alien made that apparent. Aliens in pop culture actually are depicted as evolved humans. You know, with the lack of hair. Of course, it didn't really show evolution as these guys kept dying.
