How collecting balls works in Playrooms

In Playrooms you collect scattered balls and bring them back to the ball pits. According to the developer, full ball pits unlock new abilities, and the balls you collect also act as currency. Collect enough and you can afford the key to the next area, where the same job continues in a new room.

The store says there are over 200,000 balls in total. Nobody tells you why the job exists, and the story is left for you to piece together.
