Control your dummy as it races through an endless lobby in this casual arcade runner. Keep moving, stay focused, and get ready for the next choice. When two mysterious doors appear, you have only 8 seconds to react and pick the right one.

Choose the right door and keep running. Choose the wrong door, and your run is over.
