Sorry... I didn't mean for him to reduce the action but, i think the action is cool!

but when there's lots of tanks close to each other, I'd never know if I hit a tank or not...
Maybe it's the (very cool looking!) effect that occurs when you hit the ground... it's great, and very fitting, but playing together with all the other particle effects, i for one would loose track. Different color lasers would certainly work towards an easier-to-overview game as well...
maybe leave it the way it is, and just keep in mind, when adding more effects, that the user will still want to know who's lasers those on screen are, who's exploding ... etc
