PC CONTROLS: A/D to rotate, Z/X/C for engines. MOBILE CONTROLS: use buttons NOTE: trajectory isn't always accurate since it doesn't account for the Earth's atmosphere or the moon's motion. a spaceflight simulator, complete with 3 engine types, trajectories, atmospheric drag, and even a moon to land on! The penultimate challenge of this game is to orbit the moon. It's VERY DIFFICULT (but possible) to get a lunar orbit stable enough that you can afk for a while and you'll still be in orbit around the moon! It's FAR EASIER to orbit Earth instead though. might add reentry heating at some point idk
