The NPC in each level are the entities that spread. -Dust bunnies leave behind dust, which has a chance to spawn another bunny -Slime go around eating flowers, which cause them to reproduce. -Ghosts spread on a countdown timer.

The Player controls Vlad, a custodial engineer assigned to remove propagating filth from various environments. Vlad is equipped with a high-tech vacuum. The filth must be deposited into a Transmutation Collector, which converts the filth into Energy that he can use to Upgrade his vacuum.

You can upgrade your equipment to collect them faster, or try to control the spreading by moving objects around to form a wall that block them in an area!

The vacuum has a dual function: Vacuum, and Blower. Each of these vacuum functions can be upgraded via the Transmutation Collector.

The object of the game is to clean the room as fast as possible, transmuting as much filth as you can before the timer runs out. Your score is based on the amount of filth you clean up, in the allotted time. If you clean all of the filth, before the timer ends , the score is stored, and you are returned to the Level Select Screen. Once all the levels have a score and time stored, you are brought to the High Scores screen.
