Unfortunately we don’t have an official multilanguage translator, I will answer you in English in order to avoid translation errors or any misunderstandings.
In case you’re asking if the save files from the previous build still work on the current public build, the answer is depends. Saves from 0.2.0 are compatible with the latest build 0.2.1. If the save was made on a version older than 0.2.0, then the saves are not compatible on the latest build.
