A single-file HTML5 canvas application (~1200 lines of JavaScript, no dependencies, less than 50KB in size): in a randomly generated universe, you pilot a ship using Newtonian physics: gravity pulls you in, atmospheric drag slows you down, and you have limited thrust fuel that depletes your score when used. Don't crash! It's a proof of concept, a game created with Claude AI in about 10 minutes (and further enhanced).

The outher limit is too big for my mobile.

Does the atmospheric drag apply only in the circle? Perhaps you can paint it in very dark blue.

Yeah, it’s not really optimized for mobile, most of testing was done playing on a computer, with keyboard and proper display. I think it’s not really suited for mobile, it’s frustrating on a PC as well, I can’t see myself playing it on mobile.

Yes, atmospheric drag applies in the circle.

Oh, it's much easier on the keyboard.

Minor feature request: In the start when there are three buttons to pick the mode, I 'd like to use the mouse.

Big feature request: I made a similar simulator a long time ago, and I wished to add an option to show the expected trajectory in the future as a help. Also, show the trajectory in case I press up and in case I press down, so I can get some intuition about the change of the trajectory. (I'm not sure if it's possible to do this fast enough. I never added it to my simulator.)
