Very hard game—no permanent upgrades – Space Gunner Pro Game - Fight aliens, win battles and conquer the Galaxy on your spaceship. Free! Review

Tough space shooter, but none of the upgrades you buy last (worthless expense). Save your in-game coins for "buy life for 100 coins" if your ship is destroyed.
