Kinda fun. I believe you just made this to test the scenarios for the main game, am I right? I'd complain a little about camera not coming back at the beginning of a new turn to your units or that your units UI picture can obstruct the playing field but it's fine as a test field.
I always question the balance of units in tactic games, since your basic opponents can die in one hit you can basically tank low opponents with the one with the highest health. Now anime girls don't convince me they can survive a gunshot wound. Third mission was the most strategic one for me as I was trying to keep the low health sniper alive, while plenty of enemies were closing in.
I'm rambling though, my favourite tactic game is Incubation, your units can die in one hit at the beginning but then most of your opponents can attack only in close range. I don't think that can play out properly in a warfare situation.
