Keep enemy Hues from reaching the bottom of the screen, and let friendly ones find shelter and safety behind your laser shield. But beware, enemies might become friends and friends, enemies.
You only have to swipe your finger right and left to move the shield and stop the Hues of the wrong colour. Try not to let more than three pass through or it will be game over!
Collect coins to power up bonuses and change the spawning frequency of each one of them in the shop.
How long can you resist the indomitable strength of the Hues? Lets make a bet.
