The game seems ok...
But the resetting of the progress ruins it.
The guys don't go after who they need to go after. I'll drop a guy behind someone I need taken out, and they'll pass him up to go after other people. If I can't destroy who I need to destroy, it's bad. If I lose and then lose all my progress, then that's no fun. Games that aren't fun don't get played.
Thanks for the feedback. Hmm, maybe you are right, resetting of the progress could have been there only in hard and insane modes and not in normal mode. Unit AI, most people have liked, some have complained (with the analytics data gathered from game and feedback from a lot of different people). But I believe its really hard to make the AI that everyone likes. I will take care of things with broad perspective (like this) to handle them with extra care.
