Wow I really liked this game! It reminds me of this strange game I found a a couple of years ago called Glitchhikers where you drive on an infinite road and talk to strangers you pick up on the way. But yeah I really enjoyed how the player got to choose to branch off the story depending on what junctions they took. A really simple mechanic that is incredibly effective at making the player feel like their actions have consequences. Really nice work!
I think you can find Glitchhikers on Itch. You should check it out if you want some inspo if you choose to keep developing this.
