Oh, this is some wonderful stuff. Interesting combat system (though I was a little unclear on just what Water/Stone were actually doing and how they were helping me, although I was on the Turn Mode rather than Active Mode; maybe that would make a difference), and some lovely artwork for the whole thing.
That said, I will say that a couple of things disappointed me. First: While I love all of the looks that were there, I was a little disappointed that only the Goth and Dancer ones were available as ways for one to end as a doll. I totally get why Dancer is where it is; there would be a lot of extra artwork needed otherwise. However, I was more than a little surprised that only Goth ever happened with the earlier situations. Given that the ending screens for the doll endings don't make it clear just which doll is Mary, I might have expected it to be more random. Or maybe I just really wanted to run around as Princess Mary for a bit.
Second, and this is perhaps more of a nitpick, but: If you lose in a battle against one of the Resin Dolls, while the transformation you undergo into a doll is different, along with the character artwork being an alternate hue, everything after you regain control of Mary is simply a replay of the normal Doll ending path. It seemed surprising to me that Resin Mary would remember having undergone the same plastification process that the normal dolls do, along with subjecting her sisters to the syringe rather than the same process she underwent. Similarly, I might have expected different ending text (and perhaps a palette swap on the ending screen) given that the Resin Dolls are explicitly described as being a sort of warrior caste within the Manor, as opposed to the lesser dolls running around alongside them.
Also, though maybe this is just me not quite understanding what's going on, is there somewhere to view all the endings, or do I need to have a big pile of save files for that?
One last thing: I wouldn't mind it if there was an Endless Mode of sorts that unlocked upon reaching endings 5, 6, or 10. Could be fun to have something akin to the way that House of Pandemonium plays in Corruption Mode, where you can train up your own plastic army. Maybe get to know Eileen a little better at the same time... :)
