This is a pretty cool game! The biggest thing I'd say could use improvement is... well to borrow a phrase Mark's used in the past, "game feel." You do not feel more powerful when you get a medium-sized mook under your control than you would a small-sized one. And I think that's because the HP requirement is static, like it looks enemy HP needs to be below 20. So the big strong armored guy, who is much larger than the smaller enemies, dies in one hit that is easy for the enemy AI to land. I don't know what the code looks like, but I think making the HP requirement a percentage of the total might fix this game feel issue.
Overall, though, a very good game! I would love to see this further developed, with more levels etc., after the jam!
