Thanks for the detailed review!
We are aware that the game needs balancing. I mostly know about all of the problems that you mentioned, and we're already patching the game and making it more enjoyable, but we can't update the game's files because It's against the rules.
We planned so much more for this game than we manage put in. All of your points are valid and we already thought about these things already. It's just that when you have to program so many systems at the same time, something will (tee hee) go out of control :)
turns, 10-20 actions, 6 friendly classes, 6 enemy classes, upgrades, grid interactions... I feel like we packed more thing then we could control.
