Okay, presentation wise this game is on point! 5/5 for me.
And I really like the idea, having to learn how to safely land a plane on the fly (get it?).
However, there are a few things that don't quite work for me and that I would change.
1. The plane is too hard to control. I get that the player is supposed to feel like they are in way over their head. But it should still be managable to get a hold of the controls and actually land the damn thing within a few minutes of playing the game (like 15 Minutes, top). Or at least feel like you made any progress in learning the controls.
2. The game should pause when the manual is opened. When I started the game I, of course, didn't know what to do. So I opened up the manual, got to read for like 10 seconds and then the plane crashed, which closed the manual. I restarted and the same thing happened again, rinse and repeat. Thankfully I figured out, that you could restart the game without the manual closing. So I spend my first few minutes reading the manual while spamming R.
3. The manual is too long. I appreciate that you put some humor in the text but this just inflates the time you need to read it. Which would be even more problematic for players that didn't figure out the restart trick. Alternatively, if you want to keep the humor, make it more clear which parts of the text are fluff and which parts are actual instructions.
4. And this is a pretty small thing but something went a bit wrong with the scaling on the manual, some of the letters and sometimes whole lines were half missing.
This probably seems like I didn't enjoy the game, though I ensure you that's not the case!
I had fun reading the manual und fiddling around with the controls a bit to try to get into a somewhat stable flight or at least crash as spectacularly as I could.
I think this could be a cool and actual learning experience with more usable controls, so you are actually able to (at least on a basic level) learn how to fly a plane. And maybe with some other aircraft or even land-, water- or underwater-vehicles, too!
