The game play was a lot of fun. I like the sprite art, it looked great. The tank was nice and responsive and it was easy to get the hang of right away. I think the sound effects need to be taken up a notch to make it more beefy sounding, would have added a lot. You may think about changing the color of the health bar to make it stand out a bit from the background. It would be nice to have some sort of an ammo indicator to let you know when you can fire a cannon shot, or when you were almost empty. Great Job.
