- Use arrow keys or WASD to dodge the circles that randomly fly at you. - Press Space to shoot a projectile that removes one of the circles. - Every 30 seconds (indicated by the yellow timer bar), you get 2 more projectiles and the speed increases. Fun fact: This is based on an old mobile game I made during my freshman year of highschool (which I never finished, by the way). Even the music originates from that game.
