First of all, I should inform that I am not a professional translator.
Even though the gameplay doesn't have any RTP elements in it,
The game's resource, for some reason, still requires the RTP data.
Since I don't want to mess up the game by poking things I don't really know,
this is going to be the safest, yet not really the best option.
As for the issues :
a) There is nothing I can do with the UTF-8 related stuff; I am no expert when it comes to those sort of things.
Deleting the 明 was the simplest solution, since it wouldn't make a huge difference.
Also, some of the missing texts were intended : http://i.imgur.com/PeGQlbs.png
b) Is there really no music? There should be. Something's wrong there, is everyone having the same issue?
I swear I saw the musics compile correctly when I was doing the compiling thing...
c) ::::SPOILER ALERT::::
d) Yes, I was hesitant to put the 'Point & Click' tag at first, but despite the game not using any mouse controls, the game uses the same system as a point&click game. This... should be fine, right?
Thanks for the detailed information!
The game files should be updated shortly.
