The game still needs some tweaking but its getting there.
Lovely small game for a small and good price.
+ Updates are making the game better and better.
+ Devs are listening to input.

- When you have a lot of airports and planes the game can start getting buggy and crash. There are no auto saves so make sure you save regularly or you can lose quite a lot of progress.
- When there is a weather event in a city, it doesn't "disable" the routes but deletes them, including all the planes you had on them. If it's a big city you have to remake all your lines and buy new planes.

This game will entertain for hours and hours.
