Decent game.
The animations were smooth and the art was very pleasing to the eye. The whole idea of a SuperTank (which you'd expect to be completely hi-tech) is just hilarious. When compared to the mini-bosses and bosses, it's an oxymoron because it's a Small AND Almighty means of destruction; Almost like a "Oh, hey, Dad. Look who I beat up!" kind of feeling. I just love it.
Only negatives I can name are the time and difficulty. The Tank was very slow and had no means of protection. In other words, some parts were impossible to leave without a few scratches. The game was also short. I'm expecting some epic game, but all there is is about five levels. I know it's difficult to make a game. I'm guessing twice as hard as an animation, since you're combining the latter with coding. But, if you make a sequel, I hope that there will be more action.
