Ah, sorry! I forgot Ren'Py archives the files by default. You can google a tool to unpack them or wait for the version update. The good news is I've been working on it every chance I get, so it shouldn't be that much longer. The possibly bad news is it's definitely going to require a new save anyway, mostly because I had no idea what would or wouldn't break save compatibility when I started making this thing. Oops.
