This is a shooting game.Your ship is a yellow triangle.
By dragging it, your ship moves around. By touching it, it automatically gives shots.If a shot hits an enemy or a bullet, these turn into stars.
To gain sores, you need to catch stars. You get 10 score by each star. If your ship touches an enemy or is caught by a bullet, it is game over. You need to survive 120 seconds to win. A timer is at left top corner. The score is at right top corner. These bullets chase your ship around. After 30 seconds pass, the game gets more difficult as more enemies come in less time interval.
Good Luck!
