Hello!
Yep, that was me! Unfortunately, I put the walkthrough on hiatus for quite a while because my life started getting a bit more hectic, and when it settled down a bit, I started getting into other games and kind of lost interest in this one for a while. I had to be away from this game for well over a year before my interest could be sufficiently restored.
And now that I'm back, I'm happy to announce that the progress on the walkthrough has been officially resumed! I've already written out quite a few more of the optional post-3Dazer quests and such, and I've also been trying to arrange it all into a somewhat-sensible order. I just have a few more sidequests to cover, and a couple other things like the Solo and Drembacher Theme Tournaments to wrap up, and it will finally be complete!
Also, now that I can edit the database, I've been thinking of correcting some of the mistakes and glitches in this game, to flesh out some of what was rushed towards the end, but I'm not sure about releasing it to the public unless I could get approval from the developer, so... I don't know about all of that yet, so I'm focusing more on the walkthrough for now! Hopefully it will be done pretty soon! Sorry about the long hiatus!
