Thank you for playing!
I believe the issue with the quit button comes from the fact that this was developed to be a desktop application, and I didn't consider how that would affect the webGL build. As far as the ship controls are concerned, I 100% agree with you, the controls don't feel like steering a ship, and if I were to continue development, this would be the first thing I'd tweak.
I appreciate the feedback you gave, and I'm glad you liked the concept!
