This test build was initially made ONLY for testing and it's NOT an official demo or release.
For now, the only thing that you can do (without breaking the test build) is test a short level which ends pretty quickly and see the controls.
To see the controls, go to Settings and then Controls.
To start a new game, go to 1 Player and then to New Game.
