Ok, this is a very funny idea, I enjoyed this! My only real gripe with the game itself is that the font and some UI was a little difficult to read, but I can look past that due to the short time constraint that these jams have. Anyways, I could see this being developed into one of those games with multiple different endings depending on which routes you take. It will be interesting to be a side character in a main game and slowly develop your relations with other characters as the main character progresses the story.
Oh, the lack of sounds and the static window was also a bit annoying, but it didn't hurt the experience too much. It was a bit too short too. Other than that I think this game just needs a lot more polish, development, and time for it to truly shine. Good work!
That aside, you could even experiment with the idea of literally not being able to have any free will due to being a side character. Maybe some actions are just completely blocked because the main character won't allow it. Finding ways to disobey could be a primary game mechanic and it could turn into a fun little game. Good luck in the jam! :)
