Very interesting.

Please consider implementing gravity for the planet and perhaps a time scale option.

I got the impression there was gravity, both from playing, and from the name of the page containing "Gravity" in it.

You are not very observant then.

Hey, don't be mean.

There's gravity from the sun but not the planet, and yes, that ought to be worth adding. I'm not sure what'd help the most to turn this into a fun game, though, so I'm working on other things. Thanks for the suggestion; a time control's probably a good idea too.

Ah yes some kind of normalization for the sail's velocity would be cool. The whole systems dynamics gets a lot slower as you get away from the sun, so it gets frustrating to see what happens with those; and it is hard to execute manuevers near the sun. (Maybe normalize for constant angular speed and display e.g. 'Time at 3.5x'?)
