This would be an INCREDIBLE learning tool to educate on geography. You could even add difficulty levels, such as displaying major roadways for an easier challenge.

this could totally be a calm game with nice music and simple tasks that you could play for hours on end, gaining more money and buying cooler planes and stuff. I would really try to avoid enemies / pirates because it doesn't make sense and it takes away from the calm, simple nature of the game. The game could still be challenging and fun without them!

He’s like the bob ross of coding he’s voice is so comforting along with the music

This game could become really engaging if you added some "learning" mode, where players are guided to the destination (with some form of arrow, minimap or whatever) for the first few flights, so they have a chance to memorize the locations of the countries/cities. And this could get gradually more difficult, starting with the big, well known countries and proceeding to smaller countries along the way.

This is so good. And could be really fun!

Some things that could add some fun:

Logic analytic, sense of humor, creativity and humbleness in this dude are far beyond the imagination...

So, here's a suggestion: you can have different difficulty levels. Some cities are better known than others, so on the easier difficulty settings, you get big cities, like London, Paris, Barcelona. Everyone will know where these cities are. Then when you move to a higher difficulty, you add smaller cities to be found. This gives the player a sense of progression. Maybe on day 1 of playing, you can only complete level 1, but as you learn where the smaller cities are, on day 2 you might complete level 2.

@Sebastian Lague: there is a large community of people playing a game called Geoguessr. Your game's gameplay could cater to them. There doesn't need to be fighting and shooting. Exploring the world is a great adventure in and off itself, especially with more details/specifics to explore (e.g. you could introduce landmarks, vegetation, buildings, roads, etc)

I love the way this game looks, but as I was watching the gameplay I found myself getting a bit confused of what direction you were going. One way I could think of to fix this is adding some sort of compass at the top of the screen? Also, a visible scoreboard that tracks your best score as well as your score for the run you just did could be fun.

This is absolutely Beautiful!
