A shooter where you can't shoot… it's kind of a minimalist bullet-hell type game, where you gain score simply by staying alive. There's quite the variety of play modes, with most introducing different enemies or bullets. The doc file that came with it states you move with the keypad arrow keys, and trigger is return/space, but I don't know that the trigger does anything besides selecting menu items. It does come with a play-back mode to watch your previous game, if you want.
This doujin circle used to have a website on the Muroran Institute of Technology's website, but I'm afraid it's long gone by now.
