Really impressive game from a technical standpoint and from just how much stuff it has in it, although I found it hard to be engaged with the gameplay because Fire Emblem-style just isn't the type of turn based tactics that I enjoy. Looks really good, sounds really nice and for the most part just feels good, those screen borders are a nice little touch too.
The issue with units not being able to attack without moving was already mentioned by someone else, but my biggest issue was that diagonal cursor movement was unreliable, both on gamepad and keyboard. Made it a bit hard to get the cursor in target position when it's only one square away.
