5/5 Despite its simplicity, it was a cute game and was well-thought out. It teaches the importance of the mentioned skills and how they can be learned from others. Well, I may be just over-analyzing it, but overall, well worth the time.
With a golden gun/tank and 100 nukes, last badge is possible. Just drop a bomb every chance you get and you'll hopefully avoid UFO's and spikes. Wear a Chest Bomb also just as a precaution.
With the tank/golden gun and nukes, 3M is definitely achievable, if it weren't for random UFO's and spikes. I mean, Zilch has less of a luck factor than this game.
