I played the demo. It has some good ideas. It has a lot of problems.
Basically, it's like a combination of a trading card game and a turn based strategy game. You and the enemy have bases, explore a map, gather resources, etc. The difference is that what you can build or deploy at any time is limited by the hand of cards you hold out of a sort of national deck that you build outside of the mission.
All sense of unit power is just a straight strength and defense. When units fight, they each basically flip a coin for each point of strength and defense for each unit fight, and it goes over and over unit one side's units have had their hit points knocked off. The problem there is that the fluff and any sense of strategy is obliterated by the power of units. Weak units get destroyed by strong ones instantly, with no chance of wearing them down. And when two evenly matched units fight each other, this happens...
The really big problem is that the coins are represented by annoying dice (yes, 2 sided dice), every single round of combat and every single roll in each round requires your confirmation. And you can't retreat from battle, or quit the game until a combat is over. Basically the game takes a long time to play, and most of that time will be spent mindlessly clicking an OK button over and over again.
Cool idea, looks neat, kind of intriguing, but amateur, brain destroying execution.
