I've got another comment somewhere down there, but I have to give an update.
First of all, I was fortunate enough to have this game when it was free (and free is always worth it but damn what a free game it was!)
After always having it on my laptop (don't think I'll ever be deleting it actually), I decided to give it a revisit after a couple of years. Went in with no memory of who was who and where they belonged.
There's no need to listen to any of the songs or the radio interview, actually. I just realised that from playing it once again. There are clues littered everywhere. Everything is gotten from the text snippets and band descriptions. You can breeze through the entire thing in about 20 minutes or less if all you want to do is figure everything out (and you can, just pay attention to what's written). But you'll miss out on so much. The labour of love that went into the songs and voice acting in this game is amazing. This is by no means a shoddy game and it's more of an experience than anything else.
Think Obra Dinn, but with music. That's about the best as I can describe this little gem. Don't care if it isn't THAT replayable, I, for one, haven't deleted it yet and will continue to keep it on my laptop if for nothing else than the songs. (And believe me, in about 6 months I'm gonna forget who is who and where they go in any case so I'll be playing through it yet again!)
Tim, kudos to you and your team and the amazing batch of musicians who dedicated their efforts toward this.
