It's a collection of piano sheet music of most of the tracks from Hollow Knight's soundtrack. The arrangements are really good and accurate to the source material. And there are nice illustrations at the beginning of each piece.
I used to play for like 10+ years but stopped a couple of years ago. I intended to use this as a motivator to get back to playing the piano. Didn't work too well yet, but I'll get there soon, I hope. :D
Yes, it's from Fangamer's EU shop. Wanted to have a copy for a while, but it was in stock in the US Shop only for the longest time. Was notified about a restock around a month ago, so I grabbed a copy.
I think they don't actually have that much to sell there. The US shoo may, though, so be careful if you're using that storefront lol.
