Game Overview
An occult mansion suffers the least violent possible catastrophe: thousands of specimen jars tumble from their shelves, and restoring order becomes a tactile first-person puzzle. Jarkeeper turns cataloguing bats, brains, frogs, tongues, rubber ducks, and stranger curiosities into a cozy-cleanup ritual, though rain, haunted architecture, and sleepwalking give its whimsy an uneasy edge. You play the caretaker whose absence causes the living house to collapse into chaos, while six affectionate supernatural housemates reveal spells and explain why every correctly filed jar helps the building heal.
Each container follows a clear but increasingly demanding filing system: its specimen chooses the shelf, a bloom on the lid changes the shelf version, its color determines the row, and a catalogue code identifies the exact position. The basic loop has you gathering armfuls of physics-driven jars, reading their labels, and returning them to place, gradually turning individual rows and rooms from disaster zones into satisfying displays. Magic prevents the job from becoming pure busywork, with lightning highlighting related jars, magnets pulling matches toward you, a panic spell exposing mistakes, and automation powers that sort or deliver jars; double jumps, cooldown rewards, and upgrades make progress feel increasingly fluid.
What stands out is how seriously the game commits to the pleasure of organization without losing its oddball personality. Squashy animations, clinking glass, sloshing contents, and a mansion full of bizarre collectibles give it the sensory appeal of PowerWash Simulator or A Little to the Left, filtered through a playful haunted-house story. Chill mode keeps the focus on peaceful filing, while Spooky and Nightmare introduce blackouts, earthquakes, and stylized monochrome noir sequences that disrupt your routine. A proper ending and 3,120 unique placements give completion-minded players a substantial goal, making it an easy recommendation for cozy-game fans who enjoy systems, and for puzzle veterans seeking a less conventional sorting challenge.

My antivirus is blocking the game — is it safe?
