Really digging the game. Top notch graphics, gameplay and sounds. A few extra levels on the campaign wouldn't hurt, but I am aware the game is only a few dollars, so no real complaint there.
My only complaint is that when I'm playing either squad assault or squad assault rearmed there is no way to resume the game if it exits the app. One accidental bump of the home screen just made me lose my progress 30 minutes into the Squad Assault rearmed. That's about the 5th time that or something similar has happend, considering the squad assault can take a fair while to complete I think its unreasonable to expect that someone using a mobile device will have much of a chance to finish them without some kind of interruption, phone call, the need to plug it into a computer for some juice, etc (both of those have killed my games).
Not sure if its specific to my device or Android wide, but I'm using the Samsung Nexus S. I was always able to resume on the campaign.
