Hi,
Translation project is stopped by the dev until the game is more or less finished, we decided to remove the option to select language in the game, as people kept complaining about the state of each language, even though the game itself is not yet finished.
Currently, only English is available, once the game script is finished, dev will share it with translators and will reopen the translating project, so we will be able to work on translating the game again.
I am aware that it is an inconvenience for people who doesn't know English that well, unfortunately we're not able to do anything about this right now.
Hope this answers your question,
Cheers
