Add at least 2 insane challenges please. I finished the game, but I still want to use my army.... Or, after finishing the game make all levels un-touched (not completed) and make the enemies strongerer (3 stars all)
In each stage, maximum speed should increase with 10% Add full screen option, add levels until 10, add meteors (fall from sky, at collision, you lose speed or die). Add 1 more bonus please (hyper-speed or phantom (can go through objects)) . Please update it. I am bored to play it the 100 time, and see no new challenge.
I'm going to do that soon, don't worry.
