Have you ever heard of Tittles? They dwell in a special fluid called Ooze B-50 and offer a great time of pure fun. Three different game modes are waiting for you.

CHAIN REACTION
Meet Blasties with a very sensitive, unbalanced system which makes them explode if they hit anything in the fluid. Your job here is to create a chain of subsequent explosions in order to reach a given popping percentage indicated in the top-left corner of the screen.

CRITICAL MASS
Meet Floaties, who attract each other very strongly. When two of these species get too close to each other, they will merge into a bigger, mutated entity.

COLLECTOR
Some Floaties are just too lazy to attract each other and merge. They don't feel the urge to team up and become a bigger and stronger entity. So you have the chance to play with them and collect them into crates.
