Thank you! That encourages me a lot.
I take into account all the advice I have received since then, from the translation, to improving the endings, etc.
Regarding the music, I think that the files cannot be found in the game folder. I would recommend that you download them from the official page of the composer (here) (or here in direct link) and activate the option to play in loop from your music player.
But if for some reason you can't, tell me and I'll upload it myself to download it separately. ^^
