Hey, this seems like the best place to dump this, in 2016 me and some other people started working on a refactor of the Stranded code. While it leaves a lot to be desired, it's not /as/ bad as the original gms code. If you wanted to make a "stranded 2", you might find it useful as a starting point, or at least look at the ideas in it:
