I updated the reward progress here (see Mobile tab). Last tier, boys! YourGames overlords really baited us, Girl's Symphony style.
P.S. Just so we'll be on the same page, コルチカム (Ko-ru-chi-ka-mu) is Colchicum. For reference, scientific name is Colchicum autumnale.
Indeed. I'd be aghast if the devs just veered from something they've been [historically] doing.
Game data will be linked on both versions, so it shouldn't matter. My intel's optimistic about this, and as Wutan said, devs are not likely to complicate things here by alienating the PC users.
Speaking of "huge," devs used to hold 10-day login campaigns for certain player registration milestones, the last one I can recall being 1.727 Million Registered Players campaign on 07/24/17. FKG probably has (or should have) broken the 2 million mark by now, with possibly a quarter of them being active.
