Pretty crazy that you did this in 3 days, looks great. I love the radar sweep animations and effects. The gameplay loop is nice, although sometimes I would send co-ords and seemingly multiple planes would be prompted to come in. I guess this makes sense but sometimes it's like a 50/50 on whether to shoot down a plane that didnt give a callsign.
Anyways I think the gameplay idea is very inventive with lots of ways to expand it out, if desired.
Congrats on the release
