void tRrLM(); //Void Terrarium is a roguelike RPG set in a ruined world contaminated by fungi, starring the last human girl Toriko and a helper robot. Since Toriko is unable to survive in the polluted world, the player takes on the role of the helper robot, who must replenish the environment of the “Terrarium” where she spends each day.

In a world contaminated with toxic fungi, a discarded maintenance robot finds a girl named Toriko on the brink of death amoung the discarded junk in a scrapyard. After nursing her back to health, it is revealed that she may well be the last remaining human, and is highly vulnerable to the deadly conditions of the outside world. To ensure her survival, the robot and his newfound friend, a decommissioned AI known as factoryAI, create a refuge for her within a terrarium. To reinforce the terrarium as well as Toriko's poor health, the lone robot must venture into the wasteland to gather resources while battling the vagrant machines and mutated creatures that roam there.

Along the way, the uncertain future of Toriko's existance and with her, the entire human race, will slowly come to light...
