The description says the episodes aren't connected, it's episodic like the Twilight Zone, not episodic like The Walking Dead. I'm kinda confused that people think that expanding on the chicken would be a good idea, as it seems like a dead end if you ask me. The story was meant to be a one off like all episodes of this series. As for the zombies, they are actually made so you can run past them, that's actually how you achieve the good ending. It's intentional that you don't have enough bullets to even get through half of them. I'll take the difficulty into consideration in the next one in any case.
Sorry this one didn't live up to your expectations, but I stand by the choices I made for this episode and I very much consider it a step forward. I hope to see your review of the next one.
