This is a pretty fun and very polished coffee-break strategy game. I really like the clean iconographic aesthetic, and it feels great when your tactics work out just right and you slaughter the entire enemy force with no losses. The special orders are really satisfying to use and can really turn things around when used wisely.
I wasn't a big fan of the extremely limited movement, as it made the game feel more like tower defense than what I was expecting; this was particularly frustrating when it came to rescuing peasants. I also found the economy to be very strict, but I assume this is working as intended to put a lot of pressure on unit deployment and dismissal.
I think a possible area for improvement would be in how to play. I had no clue what I was doing at first, and it took some stumbling to work things out. There are some mechanics that I'm still not clear on, like how the special orders (e.g. Dragon Breath) are unlocked, how the "reset cooldown" banner works, or exactly what I earned from saving peasants (I think a popup hint said they give you gold, but I still always had virtually nothing after each mission).
Great work!
