You win when you assemble and complete the Rocket Capsule, Rocket Fuel Tank and Rocket Engine, which are tier 5 cards, so you need to be at least upgrade level 6 (probably 7) and then survive long enough to get the rocket up and running. Thanks for the comment, glad you enjoyed it!
I really did! Simple yet, full of strategic depth. On the comments I saw earlier, one mentioned that there should be a food/gold per turn indicator. You said it is hard to do with some of the things like hunter. You could add it in and only count guaranteed income and food generation.
