This looks absolutely amazing!
Is there a specific Renpy version requirement or something to use it? I decided to try it out, added the .rpys to my project, and when starting,g I get the following error right away:

I'm not entirely sure if it's something on my end or if I'm missing anything, but I thought I'd ask if that's okay!
It's visible in the error, but I'm using Renpy 8.0.3 by the way
