Maneuver blocks with your arrow keys to line up 3 or more of the same color and pop them.
[Q]: changes quality
The idea is to drop blocks of 6 different colors into a pool of water and match them up to score points. From the bottom of the pool, bubbles will rise up to add some complexity. You can use those bubbles to score larger combos, but only if they’re the same color as the blocks that you’re dropping on them.
