Almost 80% of the plot is difficult to continue, and we need to add some guidance to make us play better.
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.
