It's not much. Just a simulator of an astronaut in space. (Did I mention It was minimalistic?) The controls are simple. Use the WASD keys to move. In space there is no air resistance so if you are flying away use the key in the opposite direction to steady yourself. Your jetpack has a limited amount of fuel, too. Not much, but I will be using this engine in another project. Stay tuned!
All on my own. (And, well, watching Gravity for 3 times straight.)
