This is a decent game and I think its main fault is probably that it's rather difficult. You could have put more in the author's comments to describe how to play it. Of course, that can be good, because it is a challenging game. The hardest part is probably how you only have a limited number of things you can do and you learn what they do when you use them. It probably didn't go popular with some people because there wasn't much blowing up.
Well, the thing you did with the four attacks at once was cool. I guess we just wish all the levels could be like that. The music wasn't bad, but it seemed a bit generic. It's fun just to watch the tank go spinning around. Granted, it would be more fun if you could figure out how to get it in the right place, but still.
