This looks like a really neat project!
I stumbled upon this thread yesterday and it's really great how much work you've put, and are continuing to put into this. I'm just starting with the GitLab tutorial, and I wanted to let you know that for a Git cloned installation, PIL is missing as a dependency for the Level Editor. On one hand, most people using the Git installation method can probably figure it out from the error dialog, but it would probably help some beginners who are trying it out and unable to make it past the first page of Getting Started.
EDIT: I'm currently on CH.3 and enjoying the game so far. I had a question about Aura skills, is the effective range marked in purple when hovered over? If so, what are the rules for how many tiles an Aura will effect? It doesn't seem to be either 3 tiles in all directions, or the equivalent of a 3-tile move (or else I'd expect the tiles N-E-E and W-S-S of the selected Shaman to be affected).
