I really enjoy games like this where there's a balance between the real life context and simplifying them enough to have something to pick up and put down without having to have a ton of knowledge about the details.

I'll be using this to teach my kid about arrivals.

This is a great game and a lovely use of the minimalism found in pico-8.

It would be cool to have a speed indication when a plane is selected or height but that makes everything more complex.

Again amazing game for the pico
