Use the left joystick to move. Use the right one to shoot. A ship spawns every second. Every 10 points, ships will spawn 3 times before the cooldown. Have fun! ------------------------------------------------------------------ Tips: In general, don't move unless you have to. Green ships move slowly and never change course, meaning you can shoot a bullet in their path, and they will not avoid it. The same applies for red and blue ships. To deal with orange ships' erratic movement, shoot a wide spray of bullets in their general direction. ALWAYS FOCUS ON PURPLE + BLUE SHIPS
