Not the greatest.
The game was a little repetitive after you get the laser cannon. By that time, the aim of the game hasn't changed a bit. I won't bash you on the controls. I think they're perfect for a tank, if you were interested. But there were other things that bothered me. First off, it's boring. You're surrounded by tanks and you have to blow them up. The killer part is the fact that all you have to protect yourself and save lives (which I didn't understand the life system by the way) is the walls your surrounded by. And the only way to kill the tanks is to destroy your own wall. That's friggin' Space Invaders on steroids.I think it would have been more exciting if there were obstacles to hide behind, more like a duck and cover game. Upgrades would have been a help. The three unlockables were O.K. but something like extra lives, or faster shooting would be cool to get. If they are farther into the game I apologize, I only got to the first boss. It's a good platform though. I think if you build a bit more it would make for an addicting game.
