Bad!!!!
It was very fun at first, and I thought it would eventually get more difficult. It didnt get any more difficult after stage 1, and I am on stage 23... On top of that, I had all of the weapons fully upgraded by stage 12, and had the armor fully upgrades by stage 17. So the rest of the game after stage 17. Was pointless, since I had everything, and could kill all enemies in one hit. DO NOT BUY unless you like very short very easy games.
