I think that your reflections are extremely healthy and I can tell that creating something you believe in is very gratifying to you. That honestly makes me quite happy. On watching let's plays, though... doesn't it get weird? I have recently published my first game and after let's play number 10, all I can see are my own failures after a while. Through other people's videos I eventually just fixate on my project's limitations and blemishes. Has that ever happened to you?
I'm very intrigued by your games, especially how you describe this one, and I'll be sure to play soon.
