Is there intro text? I guess that I missed something.
My computer went crazy after starting the game program, so maybe I missed something thinking it was a lag.
so it should open to a menu level with the drop pod. Tap I or O or 1 or 0 to cycle the menu options. Tap both buttons I and O or 1 and 0 to select. In settings you can change input responsiveness. When you start a new game there will be a text scroll, then it will open to the desert level which is the game. Please let me know if you continue to have problems.
