I JUST finished the translated game and had come here to post about it, and lookie, it's updated with more content I can't read. Guess it's time to wait for the translators to catch up on the new content all over again, and on that note, I suppose I'll see everyone in 2020! Seriously though, thanks to the translators for doing good work. The current English patch of Plus Disk has typos and untranslated strings sprinkled through it, but at least I was able to play what turned out to be a pretty good expansion of what was already a pretty good game thanks to your efforts. I have some friends off-site also playing this so believe me, your work's appreciated by more than you all probably know.
As for the game itself, Labyrinth 2's Plus Disk wipes the floor with Labyrinth 1's in the same way the game itself does. I found Labyrinth 1's plus disk needlessly minmaxxed and all but unapproachably grindy. Labyrinth 2's general quality of life improvements (affinity hints via colored damage, challenge levels next to bosses, and visible lifebars in battle) made this one MUCH more playable without constant reference to a wiki, and I was surprised at how little grinding was actually necessary to progress. The flow in general was 100 times better, and while after beating ***WINNER*** in Labyrinth 1 soured my overall opinion on the game, I'm rather excited to see if I can beat this one's version of him and still want to start over all again, just like I did after Hollow Yamata No Orochi. I expect a grindwall NOW, but I don't think I'll mind it... Plus Disk has a satisfying, playthrough-ending conclusion as it is without the need to go hunting down the level 1000 super boss.
Guess I'll wait patiently for the next translation patch to join the fun on this new stuff. In the meantime, I have a second playthrough to finish.
