Soft Landing

You're the controller at Petal Tower, in a quiet garden. Flower airships are drifting in, and each one needs you to guide it home.

1. 1
   Listen to the pilots. Each one calls in asking for the daisy flower pad or the lily flower pad. Its tag shows what it wants.
2. 2
   Pick an airship and give an instruction. Click it, its strip on the left, or press Tab. Then use the buttons (or keys 1, 2 to land and N, E, S, W, H to hold), or draw its route by hand on the map or the radar. Either flower pad works, but the one the pilot asked for scores more.
3. 3
   Use the holds. Arrivals fly straight in and wait for you. Send any airship to the north, east, south or west hold, where several can circle stacked at different heights. If an airship reaches its pad without clearance, it goes around and you lose a few points.
4. 4
   Mind the stakes. Two airships on the move that touch get tangled. Every airship has a fuel bar on its tag that runs down, so no one can hold forever. When it gets low the pilot calls for priority. Lose three hearts and the garden closes.

You see the whole garden from above. The radar in the corner watches the wider approach, so you can spot arrivals before they reach you.

A made-up game for fun, not a real air traffic tool.
