An early prototype of a Kerbal Space Program-like game I am planning. Still buggy and missing a lot of planned features, so don't complain yet. Use the arrow keys. Press space to change reference frames. I will come back to this once all the craziness around 3d Solar System dies down.
All I changed was the amount of fuel and the arrangement for the GUI. Credit to @scratchscope11. My other account is @funkydome (there is no profile picture because it is an old account).
