I had a glitch in level 7 where one of the green leapers wouldn't die or attack. It just followed me around like a puppy and I had to restart the level.
It would nice to be able to deactivate some of the upgrades for the sake of trying to complete some of the missions. Just a small thing that kinda bugged me. Still a great game.
Nothing like forming a rank of almost 30 Frenchies then getting 4 airstrikes at once. There's a sick pleasure in watching the utter death and destruction of a bunch of near-useless units
