Story Overview:

Narration (Backstory):

On a devastated planet, a mad man Mr. GW created a powerful machine able to control nature itself all because he thought the planet was too cold. It is with this machine called the “Thur-mo-state”, with which he was able to shape the weather and all of the worlds to his liking. Causing mass devastation, Lakes turned to lava, Forests were flooded in thick black oil, and skyscrapers melted like wax… Literally!

In order to survive this terror, the people of this world fled to the depths of their oceans in massive bubble cities… This is ridiculous! And for a while, they believed they had founded safety until the terrors of the Thur-Mo-Stat found their way to their sanctuary.

Now a hero Must stand, A Hero Must Bounce, A Hero in a Bubble!


        The player will take control of a small elemental humanoid boy in a bubble. This Bubble protects him from the terrible environments he must venture through in order to shut down the Thur-Mo-Stat and save the world. Venturing from the Underwater city, the discoveries that the bubble he is trapped in is a strength more than a weakness.

        The bubble is able to change its material to meet the challenges bubble boy will need to overcome. As he travels collecting the pieces of from the depths of the ocean to the wax filled sewers of the lost city and into the Black Forest Of Oil where he will confront Mr. GW and turn off the Thermostat.

The Enemies:

The enemies are themed to the nature of the environment they inhabit. They should seem like monsters that came to life from the environment.
