Arrow keys or WASD to move around the maze Space bar to show or hide the settings when in the maze Maze type 1 - corridors and open spaces Maze type 2 - only corridors Keyboard problems have been reported when using the Edge browser. This is an issue with Edge and not with Scratch. I recommend using an alternative browser. The game calibrates itself for optimum performance on your computer. You can override this by increasing the graphics quality via the settings in the maze Sulfurous link - https://sulfurous.aau.at/#214586875
