I'm very happy with the new changes and additions- the extra dialogue and interactivity was very welcome. Watering Merry's plants, talking to a few NPCs... the world feels more alive now, especially the human village.
Gameplay balancing feels much better now as well, the more powerful attacks felt like they did roughly the right amounts of damage. Mystia went down very quickly, but I think that's better than being too lengthy or difficult. Yoshika felt very well-balanced and was a fun fight. At first I thought Dream Boost was kind of underpowered considering its high cost and short duration... but then I used it in the final Nightmare fight, got a critical with Shattering Danmaku, and dealt over 1500 damage in one hit.
The only real critique I have would be the same issue Adhdweirdo mentioned, the dialogue after the Mystia (and Yoshika) fights are bugged, characters repeat themselves numerous times. It's hilarious but clearly not how those scenes played out in the older versions. (I'm playing using the offline, downloaded version.)
