This game does not have the language of some countries, which makes it a little difficult for us to play, so some of the task guides are really hard to understand.
The number of languages generally depends on the activity and desires of individual community members. For example, Chinese (simplified script) is expected to appear in the stable version 0.73 because one person wanted to teach the game their native language. Polish may appear in version 0.74 (based partially on human and machine translation).
The game's creator can't teach the game to all languages themselves; there's too much text, but they add translations created by the community.
