You described the feeling we wanted to get very well: chaotic enough at first with seemingly many options, but with some exploration painting the way you can choose to follow.
Sorry to hear you didn't get an ending you wanted! Hope you'll give it one more try at some point to confirm your theory how to get it. Though I'm very curious: did you get frustrated because expected something different?
And about the hangar - yeah, I thought it'd be obvious as it's closed the same as visited locations, but probably we shouldn't have kept it on the map at all.
Thanks a lot for the comment!
