Incredible job! This is a complete game in every sense. I love the concept, the interface, and the graphics. Some thoughts:
- It was hard to find every last build site. Maybe in the build menu, make it so that buildable sites are bright and unbuildable are dark, instead of the reverse.
- The last two thirds of the journey was very repetitive. I would consider cutting the total time required in half.
- There was a lot of mismatched event text.
- The mid-end game is about managing population, but the player has no tools to do that except wait for disasters. The idea of managing population both as inputs to resource creation and sinks for resource spending is very cool -- especially with a modeled age distribution -- but the player doesn't have enough control to make that part of the game.
