Hello, game is working and is funny, but since it's advertised to be multilanguage,it will be released as such in the future, or there's a hack like theme hospital to set up a different language?

Nice, but how? Can't see an options menu or whatever it is .Maybe I'm just dumb but can't find it.

I may be mistaken about this, but I don't believe the game ever had any real options - indeed the DRM-free version I have from Humble and the Steam release don't seem to have anything of the sort.

However, you can change the language manually in the game's config file, see here as to how (this doesn't list all the languages, but we're a wiki, someone can add that!)

But maybe the GOG release is different :)

It works!Thank you very much,edited the config and it just works.

Unfortunately, it is different. GOG's release has only localizations listed in the game's readme file, and those are: en, es, fr, de, it, nl.

Can we expect addition of other language packs? I'm especially interested in Polish, because I specifically bought this game for my little sister, and she doesn't know English.

Well, that sounds like a major bug, since the store page advertises Polish as one of the supported languages!

I'd contact the support guys.
