1) Are the "flight school" levels too hard?
I think the levels are fine, but the controls are to hard. Well, it didn't help me that it took a while to find the instructions that said WASD is one way (backwards for me) and the arrows are the other way. That helped some, once I was using the arrows, but I still find the side thruster controls weird. If the ship gets off to far at all, there's just no recovering it, and it seemed to touchy to me. I can understand if you want that to be the big thing in the game, but perhaps there's a way to add "training wheel" of some sort early on, so the controls and easier at first, then get harder?
2) What level did you quit on and why?
I made it through flight school, but quite on the first level of landing school for the control reasons above. every time I would get the ship in the air, it would tip to one side, and either just keep going (I couldn't correct enough to overcome the angle) or I would over correct and get stuck on the other side, unable to get back upright. Just to touchy for my taste.
3) is the goal intuitive enough?
Only minor issue there was the ones where you need to stay in them for a while. I figured it out, but was a little confusing at first, then just frustrating cause I couldn't do it
4) most importantly, does flight school teach you to fly?
Well, it taught me what I am supposed to do, but that I am no good at it and should stop playing now....
