Thanks for the feedback!
Yeah, I see the improvement in rebindable controls, as well as a more extensive tutorial teaching you how to read the instruments and fly the plane. The latter is a job for when we've got a little less time crunch than two weeks :)
"I would have come into this expecting an air traffic controller talking me though bringing it down with a difficulty slider for how good his information is."
That also sounds like a surprisingly fun game idea to prototype at some point!
