This was interesting. I’ve also never heard of a game like this (there’s probably a niche for it! :P)
But I think some more feedback on the actions would be good - as well as a tutorial level or two. I also would have liked to have a pause button so I could plan out my actions better, although I’m not sure what level of realism you were going for.
I also noticed that every time I play, the 2nd 3rd and 4th plane always all want to go to the same gate. I think a complex collision like that would have been best saved for some of the later planes, after players get to grips with the mechanics.
