Thanks!
In theory, you can surround the spread with Eels, but you will eventually run out of moves. I didn't get to implementing a "shake up" to keep playing, but I also kind of like the idea of a game with quick rounds you can get in and out of.
Definitely learned a ton about trying to keep the game structured as it gets bigger, linking the systems without making it impossible to change anything, etc. So if I keep working on this, there's likely to be a big rework to start with, because near the end it was definitely "just get it in" :-D
