The itch version didn't load at all on Chrome under Windows 10 for some reason. On my Arch Linux netbook with 2GB of RAM it did load, but the first time I entered a city it just froze and started eating up all my ram (I was at ~2GB RAM used and 1GB swap used before I shut down the browser). In the end I played it using the editor in the source code link and it worked fine on the Windows computer I first tried this on.
I like the idea and the execution too. I was glad you didn't make the different systems too deep, which made picking up and actually playing the game easy, which of course is nice for any game jam entry. I liked the realism in the movement system and didn't mind getting stuck too much as the atmosphere of the game was really great. Absolutely 5 stars in mood. I think I might've "killed" a couple of towns by building schools too early in their lifetime, but the game said that I made a difference (got 504 points I think), so I'll have to trust it. What is the last screen supposed to present by the way? Slavery/poverty/literacy at different points of time at different places? It was hard to grasp to be honest.
With this I have played all of the Open Jam submissions (excluding Laser Eyes VR, which I don't have the equipment for and I have yet to rate P3TE due to a bug preventing the last minigame from being played). Yours was the last, but certainly not the least :).
