Very cool tactical game, very cool character classes. If you like XCOM or FTL, play this game. I have some criticisms though.

It doesn't feel like the dev had a great deal of confidence in the campaign. The story comes off as rather cheap with all the lampshading jokes and funneling everything into a fight.

Even at the highest difficulty the objective was always fairly unimportant as in all but 3 missions (you do maybe 150-250 in the game) I just won by eliminating all the enemies. It is a shame as I could see how with some tweaking a ton of potential could be unlocked.

For most of the game I was grinding exp because I was confident I could face challenges but worried a particularly hard mission would destroy my progress. However I played the "Standard" mode where the difficulty doesn't ramp up quickly (the first two difficulties are trivial).
