I'm so far removed from the game that I don't have much to add. I did learn afterwards that Eighting is full of staff from Compile, esp. Kazuyuki Nakashima and Kenichi Yokoo. (Also uh when Toaplan disbanded some people went to Raizing which is for the purpose of our discussion basically Eighting, and some of the ones who didn't go there went on to Akumi, Gazelle, and most notably Cave.) Eighting mostly makes licensed games now but did make the immaculate and unmatched non-ochimono puzzle game Kuru Kuru Kururin.
