No, anyone can play it, the update would've been more of a "fan service" much like the girl's clickable cleavage from the Epic Battle Fantasy games. But having actually looked at my re-design, I may hold off on the girl's visual update for a while as it's not as good as I remember it. The skirt seemed okay though since it was easier to draw, I may just keep that.
Anyway, sorry I kinda took over the topic, I've been meaning to ask this question for a while and this seemed like a good opportunity.
