On each level you will have a certain amount of rounds to complete to finish the level.
On each round you have to find 2 replica's of the image shown before the timer reaches 0. The time remaining from the last round will be added to the new round.
Once all rounds for that level are complete, the next level will begin with added rounds and added images.
Get bonus points for any extra time remaining and for not having strikes
3 Strikes and it's GAME OVER!
