Awesome job for your first game, really great choice adding different maps to make the game looks different.
I feel it would be different and cooler if you add shooting and maybe bosses to the game, It would make the game more immersive, but it is your first game I am really sure that you will create awesome things! This right was really great for a first game, nice job!
I also think the game was a bit disconnected to the theme, I couldnt understand if you were getting started as a pillot, or if you were starting a game dev.. idk but I liked that you at least created something, nice job and it will only get easier from here.
