If the game does not start
Cosmic Starship needs a browser with WebGL (any recent Chrome, Edge, Firefox or Safari). If 3D graphics are not available it switches to a simpler 2D view. If the screen stays dark, reload the page, check that hardware acceleration is turned on in your browser settings, and see the FAQ.
