Really cool concept, it is definitely hard to predict the voronoi cells. I think one thing that would have been nice to kind of animate the regions changing as the turn progresses, it's much harder to build intuition when you only see the before and after.
It's really interesting and I wonder how balanced it is, it could be cool as an online pvp thing like chess or advance wars by mail, you would probably have to rework it so it's more playable in 1v1 though. Also no guarantees anyone would be interested, it's a very complex and interesting game but might be too hard to understand for the average player, still really cool and I'd love to know what high level play looks like. Definitely one of the most mechanically interesting and original ideas this jam.
Also! I appreciate the tutorial, the icons are a bit unintuitive so some work could be done to make the UI a bit more clear, but the tutorial really helped me quickly understand what to expect which was great!
