Incremental-like game. You’re an airspace controller. Drones, birds, lots of things appear and you need to click/shoot/whatever them all away to prevent collisions with the airplanes.
Survive as long as possible. Earn points for each collision avoided.
Similar idea = “RADAR/SONAR”. You can’t see anything on the map. All you get is a bunch of sonars placed at random locations, sending out waves. When they hit something, it briefly shows up as a blip or outline on your screen. You must watch closely, memorize, then click exactly the right spots to gather stuff there.
Inspired by that newspaper article about keeping drones away from Eindhoven Airport. I discarded this idea myself because it’s already very similar to many existing airspace controlling casual games and I didn’t see how to really make it unique.
