I plan to center the story on Miku, Rin, Luka and Len. But of course, other characters like neru, meiko, etc, will be making an appearance as well.
also i noticed that your image folder for the game is open for browsing... this means people will most likely just open the folder and look up the images instead of playing the game :/
most games have it hidden/changed into another file type so people have to play the game to get access to the images. i recommend u look it up :D
