You are the spaceship (Which looks like the letter, 'A') Left and Right arrow keys - Turn Up arrow - Go forwards S - set high score if it isn't done yet. R - put all asteroids in the middle (WARNING - don't do it at the start.) Shoot the asteroids while avoiding them, and shoot the UFO for bonus points. IF TOO LAGGY, PLAY HERE: http://phosphorus.github.io/#89381483/
This is based on an old game, made by Atari. The explosion noise is from @m44. The shooting sound is the zoop sound from scratch, only edited. All art by me, and the asteroid shapes are from the original but re-created in scratch. UPDATE LOG ----------------------------------------------------------------------------------------V0.1 Asteroids now act like the ship when on edge V1.1 New asteroid shapes V2.2 Fixed a glitch with asteroids stuck in the corner, and added a score V3.2 Added the UFO for bonus points V3.3 A lot less laggier with phosphorus V4.3 Phosphorus is so good that I added more asteroids V4.4 I just realised that it's trickier with more asteroids, so back to 3.3 I guess... V5.4 Bullets from the UFO now hurt, and smaller asteroids go faster than bigger ones. V5.5 UFO bullets cannot go through asteroids. V5.6 Some asteroids used to sometimes not move - now they always do move V6.6 Decreased difficulty and UFO is worth more V6.7 The UFO makes an explosion sound when you shoot it
