It is indeed good! (I actually have the soundtrack on my phone.) But I suggest playing the game and letting the soundtrack surprise you. It really is worth a play.
Yeah, I usually avoid listening to the soundtrack before playing some game, but I've heard Bonetrousle somewhere, and couldn't resist buying the whole OST on Bandcamp :)
The game sounds somewhat controversial with some liking it a lot, while others quite disliking it. I might give it a try at one point.
I really liked it! Then again, I played the games it was (obviously) inspired by, and I liked those games too. I understand if people don't like it - it's pretty personal, in the way that it's targeted directly towards the niche the creators love. Those things tend to be rather splitting, so it's unsurprising, in retrospect.
It's kind of like bad shark movies - there is a group of people who love them, and everyone else is fine not being in that group. It's not that either group is better or worse, it's just a niche.
