Sorry for the late reply, was in school.
I couldn't get the sound to work in the browser within the time frame sadly, no idea why.
There's a feature that I added early on but forgot to reference in the controls- next to your spacecraft there are two colored dots. The yellow one points towards the star so you don't get lost, and the red one points to where you're going. Also, since the game in a physically-based sim, knowing how orbits work helps a ton, but i understand that the average player probably won't.
Anyways, thanks for playing!
