This game is goddamn solid, nice job! I only really have a few minor suggestions.
The time it takes for the projected path to be drawn out is a bit slow, definitely wants to be faster or even instant.
The level art for the lander segments needs work. It's not clear what objects are in the foreground or background.
The lander controls are a little strange, but idk I got used to them over the session.
Launching needs work; your lander just kind of teleports from the platform halfway into space rather than having an explosive launch or anything. The effect is a wierd disconnect between the lander and the launcher which doesn't feel great.
