More verbs would definitely give more playability, great thought! Other things I had on my wishlist were:
- optional route incentives, like point multipliers that spawn around the map occassionally
- different levels with different airport positions / multiple airports
- achievements for reaching certain thresholds
- differently sized aircraft in addition to different speeds
- limited node economy to restrict plane paths
- and more :D
Maybe I’ll revisit the game in the future and build it out a bit more! Thanks so much for playing!
