Hold the "Space" key to shoot, "Up arrow" key to go up, Down arrow to go down, "P" key to pause, "F" to activate the force field, Only if you have any force fields will they start to work. • Notes This is my original Rock Blaster's second (modification of the joystick) version. There are no levels, and force fields and money are both infinitely available. Please like, share, and comment on this game. If you can, then also follow me, please! • Updates v2.1: I have included it with a much better joystick. v2.2–2.3: Alien With red eyes and black teeth v2.4–2.6: Better moving up-down and shooting using space controls. v2.7: You will get less money if you kill the aliens, unlike earlier when you got more. v2.8–2.9: Much better and transparent-looking joystick. v3.0: A vastly improved graphical user interface (GUI). • Remember I update the game frequently enough that each update increases the version number by 1. If this is Rock Blaster 3, for instance, the next version will never be a decimal number, such as version 3.25 or 3.8; instead, it will always be sufficiently updated to raise the version number by one (always adding ten more new features!), thus creating version 4.0. #RockBlaster
