Cool game. I couldn't find a way to survive, but I think I found all the ways of dying. It'd be nice if there was a count of how many of the deaths you've experienced, for evil people.
I wasn't planning to add this game to my Favourites, but after getting the hard badge I have a real desire to continue and get all 120 awards. So, favourite it is. 4/5 rating, will 5/5 if either of my reported bugs get fixed.
On the level with the camouflaged units, once they had all died it didn't give me mission complete. I was left to shoot at absolutely nothing for all eternity.
