on some of the more complicated screens it is necessary to refuel. This is accomplished by flying to a special platform marked with an "F" and containing a gas pump. The player must pay for fuel out of the money he has earned. Passengers do not make allowances for pitstops, and their tip will continue to decrease as the player tanks up. The taxi's fuel consumption is based upon the time spent in the air, not how much the thrusters are used, so if a player needs to get from one side of the screen to the other, it consumes less fuel (though is more dangerous) to accelerate halfway across the screen and then reverse thrust, than to use one small thrust to move slowly across the screen and occasional upward thrusts to maintain altitude. After completing all levels, the player gets to a special "mystery level", in which the player is greeted with the message "Welcome to... MUSEWORLD" and three platforms, each with a figure relating to another Muse Software game: an ambulance representing Rescue Squad (1983, also John Kutcher), the Nazi soldier for Castle Wolfenstein (1981, Silas S. Warner), and a shooting robot relating to RobotWar (1981, Silas S. Warner). Development Kutcher wrote Space Taxi while a freshman at Hopkins University. The physics in the game were influenced by Lunar Lander. Legacy Space Taxi was cloned several times for the Amiga, once keeping the original name and once as AirTaxi. A similar game on the PC was called Ugh!, where the player controls a caveman with a flying contraption. For Windows Phone a remake of the first eight levels was published in 2012 as Sketch Taxi. Space Taxi 2, an authorized sequel to Space Taxi, was released by Twilight Games in 2004. It is available on their website. Space Cab is a tribute to Space Taxi created for the Atmega 32u4 based Arduboy game system. Space Cab can also be played through online emulation.
