I like it a lot!
The mood is set from the first 4 chords. Just fifths and fourths, very steady and stable. And then a little melody comes on top of it and I was destabilized (in a good way). The key is not at all what I imagined (B minor instead of A minor I think). It brings an enigmatic atmosphere.
As a fan of outer wild, I could imagine what you wanted to convey.
I won't detail everything but the rest is very good too.
Great idea the morse code in tune.
Bravo for your creation.
