Hi, DAGamerGal! We're delighted to hear you've been enjoying the X Playing Pieces universe.
Aha, yes, Ambrosia is meant to speak with a hint of an exotic accent. We believe she was trying to give some words an English slant and others an oriental touch, which didn't seem to work out so well for you! However, we'll see if she can't adjust her accent. After all, practice makes perfect. We'll probably post some audio clips over on tumblr to get feedback in the future. The team and I listen to the dialogue so many times that fresh ears are helpful! We fully believe our voice actors can do it with hard work and support.
As for Chase's appearance? His design is relatively the same (aside from the addition of his fur coat), but his leathery skin texture is being made a little more prominent. Let's see...this short piece should explain why a little better. (Long story short - his rougher appearance is part of his character. He's generally not known for being attractive on Virgo Island.) Though, we do plan to touch up his design for the full version to make sure the art's all on the same page.
Thanks for letting us know what you think, and we're thrilled you're looking forward to the full version! (We are, too.) If you have any more questions/feedback/theories, feel free to let us know. Have a Happy New Year, DAGamerGal!
