An remix of a SFS-like game I added more features to. Use the arrow keys. Press space to change reference frames. Credit to @scratchscope11 for the original project.
Added mars as a planet you can have set, more zoom (up to 15) and somewhat realistic gravity for mars. Mars also has a 2.75% slower day than earth in real life, so I adjusted mars rotation to match this, Mars has a thinner atmosphere, which I reflected too. Press "m" for mars and "e" for earth I can't run orbital projections for mars, attempted to but it is too glitchy to work.
