Playrooms (PC) Steam Gift Global

Collect the balls. Bring them back. 

Thousands of balls lie scattered across the Playrooms. Someone should put them back, and there's no one else here. Almost no one. You don't know how long you've been working here, but you know what needs doing: over 200,000 balls are scattered everywhere, and you bring them back to their ball pits. Nobody told you why.

Collect the balls. Bring them back. Fill the ball pits. Full ball pits unlock new abilities, and collected balls are your currency. Eventually you'll have enough for the key to the next area. The work stays the same, only the room changes. Tiles, water, endless corridors, a hallway with more doors than it should have.
