Bubble Hero

Bubble Hero is a bubble shooter with mice in the mix. Some of the bubbles on the ceiling have a mouse trapped inside, the counter at the top shows how many are still up there, and the level is not finished until they are all down.

The game spells out the rules for you: tap, aim and release to shoot, use the arrow to change colour, and connect three or more. Free all the mice and collect two stars to move on.

Ammunition is finite. A wooden sign beside the cannon starts at fifty-five and drops by one with every shot. One well-placed bubble took out a whole magenta cluster, freed a mouse and added two hundred and sixty to the score.

Three pages of special pieces come before the board. Rock and chained bubbles have to be broken another way, while fire, bomb, free, clear, aim and any-colour bubbles help you do it. A detonator, a laser and a key wait as rewards. Four pages of twenty levels sit behind the first.
