So I'm thinking of adding to the game one crucial part of living in the 80s which is your freaking shows getting interrupted in critical moments by commercials. Except THESE ads are funny and satirical.

Humor is the lowest hanging fruit in point and click, but the tone of the Angelgaze story is very serious and I don't want to spoil it by adding humor without good reason - so my idea is to put the funny stuff mainly inside commercials as a type of comic relief. 

I thought that characters in the story could be spokespeople for various products and services - it's another layer of narrative showing that Angelgaze is actually an 80s cult TV series like Star Trek that has made the protagonists famous, so now they are in demand to shill all sorts of stuff.

Kian could show his real ENTP self in these, revealing yet another layer, namely that he is portraying a dramatic role that is a bit more serious than his normal on stage personality (I think this is realistic for his personality type).
