You are an "elite sanitation specialist" sent to a small Balkan town plagued by an unusual type of dirt and evacuated for the same reason. At first, you blame the second world laziness and simply aim to get the job done, but soon you start to notice unusual events taking place. The whole town seems to be covered in hydrophobic coating, revealing that the people were desperate before they left, and the dirt that covers some houses has very artificial looking placement. With only a handful of people left in the town (all shop owners or employees), you are free to roam the whole area, wash and explore empty houses and buildings, find clues and hints and get to know townfolk's deepest confessions and secrets left on numerous notes.
Armed with washing and digging tools, your your primary job will be to clean the more "stubborn" properties completely covered in dirt, as well as dig through the old fortress that was the first quarantined area, and is almost completely buried underground. While digging, you will find various items you can sell in a nearby shop. You'll be forced to often improvise (ie. make the rare instances of non-hydrophobic floor wet to conduct electricity between two points), upgrade your tools and solve puzzles in order to access secret areas with better rewards.
You will also be able to upgrade your character so you can dig and wash longer, move heavier obstacles, hold more money and items. Your inventory slots are limited (but upgradeable), so plan ahead and make sure you are ready because the town will eventually show you why it really had to be evacuated.
Dirtville is ultimately a casual sandbox game sprinkled with a bit of mystery. It will show you the tongue-in-cheek version of your average Balkan country while you clean up everything through satisfying mechanics in a vibrant, stylized suburb environment.
