Do the "Play Links" option and you'll get the badge, I tried the "Play Plus" but found the 2nd 5x5 puzzle to be bugged, no matter which way I put squares it would never accept them as being right, so I gave up. 2 stars
I looked at walk-through and sure enough the game is bugged, I cannot get items out of inventory to use them. I tried reloading the game to try again and now the game doesn't load... 1 star
The 2nd monster type that appears always kills me and cannot be avoided. So 1 star, having to redo the same thing repeatedly 10x to get badge is too monotonous for me and gets very boring very quickly...
I am starting to suspect some people have some way of cheating in this game cause they hit 100% of the time, even if I move my tank. It may be possible to be highly accurate, but these people are pushing it so far that it's beyond the joke... 2 star
Instructions for this game == non-existent. Eventually figured out what to do and after many wins turned the map green, then a blue final battle pops up, kill that and you get the easy badge. I found this game to be woeful.
