I just went back to look at the old thread about the game, and it reminded me that you had a point about the 'Japanese game being made by an American' issues. A few years later, it sounds like the game hasn't progressed much from that point. That's excusable for a work in early alpha, I suppose, but it didn't say good things about how close the game was to being finished. And he did seem to be much more interested in adding new features than uniting them into a cohesive whole.
I dropped out of following the project a few years back when it turned out the lead developer was either a Gamergater or at least Gamergate-adjacent (notably griping about 'SJWs' getting his game blocked from Twitch or something along those lines), but even back then it seemed like an incredibly ambitious project that had a few interesting mechanisms, but loads more that needed to be done, and even more work that would be needed to pull all of those systems together into a coherent game.
