A physics puzzle game about playing with clusters of realistic soap bubbles in a microscopic aquatic world. From the unique artistic vision of designer Stu Denman and his scientist grandfather Cyril Stanley Smith. Featuring 160+ handmade puzzles and deep gameplay with surprising new challenges down every path. Fill bubbles with colored air and push nearby bubbles around using the physics of pressure and surface tension. Break edges between neighbors and mix colors to create matches of 4 or more. Make moves in real-time with a Tetris-like queue that lets you build up cascading chain reactions. Adaptive ambient music gracefully integrates with the satisfying sounds of popping. Save friendly creatures that are trapped in the bubbles and avoid greedy jelly crabs and spiky urchins. Also featuring an innovative colorblind mode.
