No problem, it didn't take too long haha C:

I am glad too that dev creddited everything, because it's always interesting to find new and obscure music from soundtrack artists, I agree that is a great song, and aside from that,  for me it fits so seamlessly with the whole vibe of the VN too.

I wasn't familiar with that term either, although certainly recognize games that use this concept on a certain degree, like the original Starfox, Chibi-robo or Animal Crossing. I guess Splatoon too, but I am not sure if the language spoken there is semantic-free.

Sorry for the late reply, I actually had to dig in inside the .xp3 files, to find the song and it's file name. 

The origin of the song is from one of the websites listed in the readme called oo39 dot com, the game has many songs from there and the intro is one of them, the only thing I could find aside from that, is that is called "YS174", no artist, or the source of the vocoder voice, or anything unfortunately. 

Also, interestingly, there wasn't any need to credit even the song, so I suppose Dendo just wanted to be sure to credit everything. 

EDIT: Nevermind, if you don't pay for the "premium" service of that website you need to credit the song, so it's actually free to use too, with obligatory crediting+link I think.

Many of the links are for other ambience songs I believe, with their sources since most of them are from "free to use". Anyways here are the OP and the ED credited at the end of the webpage den2do.com/trial.html

EDIT: I will have to reinstall the game and check about the one you asked for, that one might be missing for some reason.

Is there a 4th episode coming? Episode III was pretty good...

I am not sure right now because I don't have the game installed, but I am pretty sure there was a .txt file inside the game folder that contained every song name.
