Finished Mana-Khemia a month or two ago; haven't had time to write about it until now.
In some ways, I couldn't be happier with Mana-Khemia's (many) endings, and in some ways, I'm still a little bit disappointed.
I could tell, just from the first flashback conversation between Theofratus and Isolde, that Isolde secretly had a thing for Theo, but I was hoping she'd also end up being Vayne's mother, there's just one little problem (see next point). Oh yeah, Isolde's still one hot babe, though.
Vayne turned out to be a Mana created by Theofratus, for the purpose of committing suicide...as opposed to being Theo and Isolde's son. So...what of Sulpher then, if Vayne's supposed to be the Mana?
Are we really saying that, all this time, Sulpher was just a normal cat, and that Vayne was the one turning Sulpher into a demon sword, through his own sheer force of will? I don't know about you, but I think it would've been more interesting if Sulpher had actually been a Mana, and ended up dying to protect Vayne in the end...because he's such a noble cat. And noble-minded kitties do things like that. Besides, a pet cat that turns into a demon sword? How much more awexome can you get than that?!
Other than that, all of the character endings were great, and were well voice-acted, but that's probably because they didn't need to sync their voices with any on-screen textboxes; if only for those scenes, the voice-acting sounded very fluid and natural. It flowed very well, and the jokes involving each of the characters, I thought, were good. Except for Jess. Jess was boring. Boo.
The whole premise of the game was this, though, I thought it was kind of...ehh:
Theofratus wanted to die because he inflicted Jess with her life-threatening illness, and the people hated him for it, so he wanted die. And for whatever reason, Vayne wanted to die, too. The whole premise seems to be, "Don't commit suicide, emo kid! Even if some people hate you, you're still going to find people who like you!"
