Keita Takahashi on Official US PlayStation Blog:
"Long time, everyone! This is Takahashi.
Finally, the updated 1.1 version is ready (available now on PSN). Honestly, debugging it was hard for multiplayer as it was a hotbed for bugs. So, if you run into a bug or two, please laugh that off. Since there are more silly updates aside from multiplay, I hope everyone has fun with the game as a whole. By looking at the number of WEBWEBBOY, however, a lot of people don't seem to have noticed the updates. They may be playing something else and not know about them. But I do wonder when GIRL will reach Mars."
