Oh! I see it now. Didn't see it the first time, tbf, I didn't pay attention to the numbers and simply assumed I had to do the things displayed quickly or else the plane would crash.
Also, idk if you are planning on expanding this game, but I can perfectly see an endless mode for this one. Like you have the lights from above that display which error is triggering, you could make the error you get to be random and you have the manual that you already have in the game telling you the solution to that error.
