For reference, here are all of the things I mentioned which were changed, which I believe should have been left alone:
Because Dead Parrots will become an endangered species if something isn't done.
also...
What is the meaning of this. You wouldn't call Ran a familiar, you shouldn't call Komachi a Grim Reaper. The term is Shinigami, darn it!
EDIT: Oh goody, I've found another inappropriate substitution. This comes from Extra, so those not wishing for any sort of spoilers shouldn't highlight.
Playing and indulging one's self in Touhou should be an experience with Japanese culture, and under no circumstance should this be watered down. I don't have the time to go through every single story again to see what lines of dialogue have been compromised in this manner, but you know where such substitutions have been made. Please, rectify this situation before the final release.
Moar edit:
Why are the character names faded? I can understand why the dashes aren't around them anymore, there wasn't any space... but faded/transparent? That just makes it sorta hard to read.
EDIT: One more beef with the above image: "the unnamed hill" is supposed to be simply "Nameless Hill". As seen at the wiki:
http://touhou.wikia.com/wiki/Medicine_MelancholyNow, the reason for this is as such: Nameless Hill isn't nameless. It was once, but it became "Nameless Hill" because the mothers of unwanted children would lay them there to die, before they had even been given a name.
...though I'm a little miffled that I can't seem to find the page on the wiki where I read that.
