Thanks! And yes, I think there's a lot of interesting little puzzly mechanics that could add to the fun of the game. The reception so far has been really nice, so I'm strongly considering expanding on this little prototype.
The pathfinding could be more clear with a simple tutorial, but basically it works as follows: Any tile that is reachable in a straight line from the starting point of an Actor (Hero or Goblin here) gets scored, and the Actor then walks to the tile with the highest score. Every Actor can have some preferences (i.e. the Hero prefers Treasure over combat). It's a bit too convoluted to be intuitive, but I'm certain there are ways to make it clearer. I really like your idea of showing what every actor intends on doing while you're moving the tiles around!
