/!\ INSTRUCTIONS /!\ You are an astronaut flying up in the sky, but the sky is not free of dangers. Arrow keys to move (left and right). Space key to shoot. (It takes 4 seconds to reload in easy mode and medium mode but only 3 seconds in hard mode and 2 seconds in extreme.) Avoid the red monsters and the edge of the screen. You start with 20 bullets but you get half a bullet for every kill. You have three lives but there is a rare type of monster that gives you an extra life if you kill it and have less than three lives. (Max is three.) Try to survive for as long as possible! The game gets harder as you play (roughly every 30 seconds). There are 4 difficulties: easy, medium, hard and extreme.
