Cool idea! but I think some of the bonus cards make it a little to easy. At first I thought the cards where a daily bonus that should only work for that specific day. I think that would've incentivised more planning and prepping across days. Like, today I got a bonus on harvesting, so maybe I should harvest a lot today instead of crafting/selling.
really cute drawings of the dragons by the way :D
Conceptually I really like a town using the dragons resources and the dragons tolerate it for the exchange of taxes.
