Thank goodness for your obsession.
I hadn't planned on making hitsounds to be honest.Yeah, to be honest it can kill a really nice clean skin if you have to mute the sounds. I'm sure there are times where they can be great (EBO, Ouendan, Taiko) but this just isn't one of those times. Touhou is all about the image. And changing just one of the hit sounds makes it feel kinda weird if the rest are unchanged.
(Conversely, This sentence will be seen strange English ...my English is poor. )
Because Japanese used for the menu etc. is a little unnatural, I proposes to change it as follows.
-Quit and Return to Title
-Return to Game
-Retry this Game
current "向こうへの ゲーム、"
amended "ゲーム オーバー"
(Is the character correctly displayed?)
