Now that the game has a clear objective, it's time to make it more interesting. Let's start with the battle system!

If you move to a tile with another player on it, you get the option to fight them! Now, that's one easy way to turn them against you.

This is a bit tricky to design, because now we'll need a second player to play out-of-turn. And since this is an online game we're making, we need to keep in mind that our laggy (or sore loser) friends could go offline at any moment.
