About
Dive into a highly satisfying first-person puzzle-simulation game where you battle devastating urban floods block by block. Armed with everything from simple rakes to heavy-duty submersible pumps, you must strategically manage dynamic water flow to clear submerged streets and restore order to a city in crisis.
Story
Following a massive landslide that cuts off external aid, your town is completely overwhelmed by rising waters. Playing as 'Plunger Guy,' an anonymous handyman, you begin a gritty hero's journey to save the isolated neighborhoods, guided and celebrated by a witty local radio host tracking your legendary progress.
Gameplay
Experience relaxing yet strategic 30-minute sessions of physics-based water management. You must meticulously select your tool loadout—bringing shovels for diggable ground or generators for night operations—to unclog storm drains, pump out flooded zones, and outsmart complex fluid dynamics.

The creator jokingly stated the game is meant to 'make amends' for all the times players purposefully flooded their cities in SimCity.
The protagonist is affectionately known only as 'Plunger Guy' throughout the game's lore.
