Oh my goodness! Elmer Fudd. That definitely isn't the intended effect, but I'm sure Ambrosia's voice actress will get a good-humored kick out of the comparison. When we were going over it with her, I believe she was trying to make it both English and oriental. (Some oriental accents touch on the r's, but since we wanted her to make up the accent, she must have adjusted it and made it sound more like a speech impediment unintentionally.)
We'll definitely let her know to touch up the accent, so that it's not giving off Elmer Fudd vibes. Of course, if the changes still come off as unappealing, there is actually an option to mute the voices in the Preferences screen. This way, you'll be able to enjoy the story without worrying about it.
I hope you have a Happy New Year, Pixel!
