Hi Tchey,
Apologies for the delayed reply! We didn't get a notification of there being a new post in this topic. We're glad to hear that the crash seems to be gone, although it's a little concerning that we don't know what caused it to begin with. We'll keep looking into it, and see if we can find the culprit!
In the meantime, we're working as fast as we can on a Linux build. It looks like GameMaker Studio 2 supports Ubuntu export, so we're hoping we can have that working in the next week or two. We'll also be pushing at least the start of Chapter 4 very soon!
