I have never released a game on GOG before, I need to look into that. The game has a few languages already other than english: you can access them in the options
You may be a bit angry with me, but my language (Polish langueage) wasn't included, which is a pity, because the game is quite original, but it's the language barrier - the lack of Polish language can hinder its reception too much, because there is a lot of text, and Polish YouTubers are also tired of the constant translations and are starting to skip games that have a lot of text and don't have Polish available.
