I think that the game is kinda clever, I like the idea of "talk" button not working at all.
Because when you first notice that it isn't working, you feel like something is wrong, like it's a bug or that you, the player, made some weird mistake.
But then you press it again and again, and again and still nothing happens, even though it should. And after a while, you realize that you aren't able to do anything and you feel like you are just stuck in this wasteland, unable to proceed, with those figures all around you, that you really want to get to know, but... you know that you can't.
Or at least, you can't in this game.
Also man, that music in the background, or whatever it is fits so well
Did you made it yourself? If not, what's the name of it?
