Oh and also for Polish speakers - there is an absolutely fantastic "superproduction" audiobook of it, with background music, sound effects and famous actors narrating, it's a treat, I very highly recommend it.
This is fascinating! Stunning art and close to the color palette I had in my head for it. Knowing Bealrusian and having read the book years ago in Russian am tempted to give it a shot.
I have no idea how hard it would be, I've never tried to read Belarusian or Russian (I guess mainly because I don't know cyrilics). But just as I wrote in a neighboring comment, maybe you could use Google Lens or something like that as an aid?
Linguistic distance from Belarusian is not that large although the languages have quite a few deceptive "false friend" words/expressions. But at least I could understand the text shown in the presentation video. And it probably helps I read the story before.
BTW, for Polish users--there's a comic book [1] that makes a nice gift (tested).
