Friendly reminder: Alchemist's promised demo of the PS3 version of Gal Gan hit PSN. It was joined by four custom themes. The demo is free, but the themes cost ¥200 each.
Alchemist also released a Flash game called Suke Suke Shooting. (If you're surprised by this, it's because the Flash game was originally scheduled to be released tomorrow.) The game has you blast four Gal Gun girls with mouse clicks, making their clothes disappear with each strike. Access the game at at the official site
