I really like synthwave. And with your OST, we are served!
There are some excellent things. For me, the best is the intro to "Impending Doom Approaches...".
I took the time to listen to the whole thing, and in the end I came away with the impression that it was a bit long. Some of the music stretches a bit too much sometimes, yet the themes sound good. But either the variations are maybe too timid, or there are too few of them.
I'm just one participant among 150 others, and my opinion only applies to me, but I think you could do with something shorter and richer.
On a positive note: I was pleasantly surprised by "Good News", and I liked the arrival of the brass section.
I hope you don't mind for being so direct.
