Beat the game. It was fun, but it has some areas that could really use improvement, most notably the AI. Because the AI is so tactically inept, the strategy around difficult levels (like the boss) involves less concern around what the enemies could/should do and more just hoping that they don't do that. With the boss as an example, he only used Rally a handleful of times before wandering towards me, whereas if he rallied every turn until he needed to run from my sniper the rats would have easily grown large enough to break through my defensive line. Other examples include enemies moving to the leftmost square to block their own allies and let me fight them one at a time when they could have moved to surround me instead.
The other big thing I noticed was that there's no reward for battles, so there's no reason you would ever pick a battle over another kind of reward, but battles appear next to other rewards as an option sometimes. It also seems to be random whether you get offered rewards or not; I got 4 rewards total over the entire game: 1 attack up, one additional character, and two moves. I was also offered one health up and 1 additional character at the same time as the damage up and previously mentioned additional character respectively. This was more than sufficient to make every level a cakewalk with the current AI, but it did feel a little disappointing due to the infrequency of team-construction decisions.
Nevertheless, like I said, the game was fun, and I look forward to its continued development.
