There is this other Game Atomic Canon where i wonder if it´s from the same developer , because it is so very simmilar. So This one here is better i Think, but Atomic Cannon has much better graphics. a very good Idea would be to have your own Music instead of always this same Atari like dideldi noises and the only Option is to turn it off.
Well none of The Developers of wither Games seems to like to write Emails...
