Fairly intriguing concept. I feel the mana cost of 30 for many spells is too much, as the game is usually over before you can even collect that once. Perhaps instead of lowering the cost, having a spell to spend food to get mana?
Few problems: Orlando says "Washington D.C." when you travel there. I think it would be a bit more fun if there was a set goal (like saving up to purchase a house, or buy up land, or something) instead of just going until you can't afford gas anymore. Solid starter game, though.
