Gary Berge, a mechanical engineer, created the new cabinets with a rotational molding process. This plastic model was dubbed the 'Duramold' unit. Īnghelo designed the artwork for the wooden cabinets as well as a new cylindrical, plastic cabinet. Once the joystick returns to its neutral position, the bubble will coast as the velocity slowly decreases. He programmed the bubble to accelerate in the direction the joystick is held. The control scheme allows the digital input to operate similar to an analogue one. Kotlarik designed the protagonist to have fluid movement like it was traveling on a slick surface. Python Anghelo furthered the concept by creating artwork and a scenario. Inspired by Pac-Man, he envisioned similar gameplay in an open playing field rather than in a maze. The initial concept was conceived by John Kotlarik, who aimed to create a non-violent game. The game uses monaural sound and raster graphics on a 19 inch CRT monitor. Entering the drain while the bubble is too small costs one life. In addition, whenever the bubble has a face, the drain flashes green, giving the player a chance to enter it and skip the next level. At this point, if the bubble is large enough to have a complete face, the player moves on to the next level otherwise, one life is lost and the level must be replayed. Ī level ends when all of the point-scoring objects are gone - either lost down the drain, cleaned by sponges/brushes, eaten by roaches, or absorbed by the bubble. The broom can be acquired by running over a cleaning lady who appears in the sink from time to time.

Contact with a blade is always fatal, while the bubble can safely touch the roach only while carrying a broom, which will kill the roach with one hit. Two other enemies in the sink are stationary razor blades and roaches that crawl out of the drain. Sponges and brushes can be knocked into the drain for bonus points, eliminating them from play. In this case, the enemy will be knocked away and the bubble will shrink.

Touching either of these enemies costs a player one life unless the bubble is large enough to have a complete face. At the same time, sponges and scrub brushes slowly move around the sink, cleaning it on their own in competition with the player. As the bubble absorbs more objects, it grows in size, eventually acquiring first eyes and then a smiling mouth. The object is to clean a kitchen sink by maneuvering over ants, crumbs, and grease spots to absorb them before they slide into the drain. The light blue bubble (center right) avoids brushes and razors to clean up ants, crumbs, and grease.īubbles is an action game where the player controls a soap bubble from a top-down perspective.
