Pong and Space Invaders had a baby, and it’s called ReflexION.
Mouse to move, Space to change color. Reflect the bullets back at the enemies – use momentum to aim! Shift to fling bombs, control to activate super mode. Go to settings to change to keyboard controls.
To get a perfect level, keep your multiplier throughout out the level, i.e. kill every enemy and don’t let any bullets past.
