Fun game! I played the 1.4 version, and I had a printer handy so I was able to print it out and do it all physical, with cards and dice and everything. I really appreciated not having to read all the rules to start - it made the game really approachable. I played three games in total - the first I lost after about 15 cards, the second I lost after only ~7 cards, and then the last one I won. The game definitely feels like a struggle for stability, and in that regard I think you nailed the theme. Well done!
As far as critique goes, there was only one interaction I wasn't really sure about how to resolve. In my first game, I had both Nuhasse and Kizzuwatna occupied by the Assyrians, and then a Sea People raid happened on Nuhasse. I wasn't sure if the "weakened" tile on Nuhasse was supposed to apply to the attack on Hatti, though ultimately it didn't matter because I rolled a six and lost anyway haha.
Overall it was a good time! I can tell a lot of thought into the mechanics and making sure they were well-balanced. My winning strategy was to put two cards on famine and sea raids each, and then do my best to survive at least one Asyrrian advance. Once I survived at least one, I knew I was safe from that loss condition (since there were only 3 cards that caused it in total), so I was able to focus on just defending Hapalla and Kizuwatna while keeping my farmers afloat. Great job!
