Have you ever dreamed of making a shoot'em up, but never succeeded in forming a group? A game editor like Yoshida Konzern might be the answer.
Imanok thought up the idea to collectively make a new game by each contributing a level. There was one catch: Yoshida Konzern's interface was in Japanese, which makes it hard to figure everything out. But now a first release of the patch is available! Over 90 percent of the menus have been implemented. The translated help texts haven't been inserted yet, but they will be in a future release.
