Round and Round Inc.

One door. All of humanity.

A corner shop, one revolving door and a handful of customers. Turn the door and people come in, and every one of them pays. Spend the money on a bigger door, new blades and more visitors. Before long the little door has outgrown the department store and the headquarters tower and is pumping in the crowds of an entire city.

How it plays

• Draw circles with the mouse to turn the door yourself, or leave it to the automatic drive. The force of your hand builds up in a flywheel.
  
• Promotion, gears, automatic drive, door expansion, blade replacement, admission fees, group admission: every upgrade visibly changes the door and the crowd.
  
• From straight blades to scoops, impellers, spirals and turbines, each blade shape handles people differently.

• Turn too hard and people go flying. Don't worry, they get back up and get back in line. Fling them in a row for a combo.

• Buses, subways, trains and planes bring visitors, along with idols, tour guides, festival parades, couriers and repair robots.

• Reopen the company to collect Spin Energy, take on perks and contracts, and come back for a bigger run.
