I really hope this game didn't end up like the previous one, if they keep on having the same micro transaction tactics they have on the original one, this game won't get past next year.
The game is an interesting distraction, though not worth it to sink your time into. It has a very bizarre progression system, in which certain game mechanics("Equipping Gear", "Fielding Party Members", etc.) are level-gated. Moreover, it takes ages to unlock those risque CGs. I thought Koihime was grindy, but this game is on another level.
