Confused as to why the required auto splitter isnt in the resources? Where can I find it?

I've added a guide for those looking for information on that here! All you need to use it is LiveSplit and a set of splits for this game.

Sorry for the incredibly late response, particularly with the new SRC layout it's kind of hard to remember that threads exist. Perhaps you've been there already under another name, but the #sr-discussion channel in the Tinykin Discord server is probably the quickest place to get questions answered :)
