So I download this game like once every 1-2 years to look at it. The last thing I remember story wise is a big war starting. Without spoiling, how further along is the main story past that point?
Hardly anywhere. You CAN take control of about half the map, but you can't do all that much with it. The Dev's remade almost everything in chapter 3 probably twice over, so I'm not sure how long it would take to do since some content added has since been removed in remakes. But it wouldn't take long, especially if you turn off the awful combat system.
And even as a slow reader I rolled through everything added since I last played in June in about 30 minutes.
The Dev is far more concerned with repeatedly remaking the UI, bells and whistles like animated mouths and eyes or giving the npc's more lively schedules, and meticulously documenting every tiny typo fix to pad out the changelog and writing said changelog in a quirky manner rather than doing anything substantial.
It's just floundered. Chapter 3 is a complete mess that also cuts you off from almost everything done before it, and no end in sight.
