Warning about the need to land added.

"Now you should land"

The warning will only be displayed when the end of the route is reached. The warning will not be shown if the player has not flown between the finish posts. If the player's plane successfully passes the finish line, a warning will be displayed.

The hint about the need for landing is focused on the planned features of the game. It is planned to add scores for the correct landing to the game.
