It's better with Turbo Mode turned on. To do this, click the flag while pressing the Shift key, or see inside the project, and under "Edit", select "Turn on Turbo mode". Then just press the flag normally. If you did it right, the project should say "Turbo Mode" next to the stop button, and it should run normally, but with less lag.
