Its pretty good, though most of the time the gun blows up after the fourth time. You might want to adjust the gun so that it only fires on pixel of explosive. But the tank itself is quite accurate, especially when you considor that certain heavy gun models are prone to blowing up
Also, continuing on Matera's train of thought, if you wanted to improve the textures, you might want to make the treads going in a circley thing, not the same direction, if you know what I mean. Other than that, I like it.
Good start, but it needs some refinement. Gun blows up and then the whole thing (with nice fireworks lol)
