Chapters 16 and 17 are finished (8 days until release)

Chapters 16 and 17 have reverse objectives. In chapter 16 (should be the left picture), you must protect the NPCs at the bottom of the map from waves of enemy reinforcements. If you hold out against them, you win, and they flee, which leads to chapter 17. 16 is the hardest map made so far, a lot harder than 6, which I had said was going to be the most difficult. In 17, you have to chase down the fleeing commander and kill him before he reaches the bridge (which takes 11 turns). There is an optional recruit and 3 rewards for being able to push even further into the top right corner of the map and kill all the enemies before killing the boss. That objective is pretty hard, but ignoring it makes the map one of the easier ones.
