Each game uses different controls, most DOS games use the keyboard arrows. Some will use the mouse , "Alt" and "Space bar".
Bluemoon's creation of SkyRoads is a polished-up remake of the video game Kosmonaut. The three months spent working on it paid off when the shareware title was released in 1993, selling internationally and getting low cost retail (LCR) distribution deals from the U.S. to Taiwan. The game's interface was an instant hit with downloaders. The space bar and directional keys are used to create an easy "jump and move" motion. Up accelerates the ship and down slows down the ship. Meters at the bottom indicate the ship's speed, Oxygen Levels, and Fuel Levels. The meter to the left indicates the level progress, next to a grav-o-meter that describes the planet's gravity (100 is the lowest, giving a weightless feeling, and 1700 is the highest, allowing no jumping). The level is restarted if the ship is destroyed, runs out of fuel or oxygen or falls off the roads. The demo and full versions of both games are now available for download as freeware from the homepage of Bluemoon
