Overall pretty interesting and original tactical RPG. My main negative points I found are how little incentive there is to trying different parties (once you get a couple of soldiers of each class you end up using the same comp over and over) and how easily it is to screw over in a mission by getting a random crit or an enemy spawning from the side. There are a lot of things that didn't sit well with me, but I think those two are a general problem of the game.
It can get pretty frustrating sometimes, but overall is fun.
