I would like a button to give the same command to all tanks. Specifically I'd like to be able to gather them together and let them together, that's kind of tedious to do with the current interface.
But I like the game a lot as it is already.
Interesting game, very original. I think I would like it a little slower paced though and the graphics could be nicer. Also, how about some sound effects?
I agree with kiorull.
But another thing, different maps please. I think that's the reason the game is under-rated here. Not enough variety in gameplay and tactics.
