Ah ah, you got me! I initially made the "no sound in space" as a joke - and I didn't consider having cockpit sounds; that's a great idea actually ...
Yes, I removed the main engine exaust display due to a few issues. That's something I could improve in the future (including the RC-thrusters that are a bit "hacky")
You're a pro ; I already find the game challenging, but I can tweak the RC strength indeed.
Thanks a lot!
