Thank you a lot! I’m still working on the engine, a lot of things need polishing and optimizing.
Disabling mouse smoothing completely would make the camera rotate in discrete steps, which looks really bad to my mind. Guess I need to test it more in different environments. Sorry for the ESC thing - there’s really nothing to show in a main menu or etc, so I decided not to clutter with useless UI and exist right away. Didn’t occur to me that this might as well be used for pausing the game! I’ll definitely use that advice in future, thank you.
Let me explain the point about Venus: although it does have a solid surface (unlike Jupiter, as you’ve mentioned), the temperature and air pressure are too high there (due to really thick atmosphere and greenhouse effect). Thus, the idea of Venus colonization usually concentrates on stuff floating high in the Venus atmosphere, see https://en.wikipedia.org/wiki/Colonization_of_Venus
