I BEAT THE LANGUAGE LEVEL!! I beat it a few hours ago, but I thought I would post a comment right after it finished processing. I beat it with [10/10 | 10/10] notebooks and got to a prototype version of the third level. I don't think it would be possible to beat it without all of Viktor's notebooks because Marzia is so fast at the end. This was a lot of fun to beat and I might do it again, here is the link to the archive and some timestamps!
