The post credits scene had you in tears? Do you not mean the pre credits scene? If so, I agree. It was beautiful, fantastic writing.It was 3 in the morning for me when I beat it. Couldn't remember if those two scenes happened back to back or one happened pre and the other post. Either way, sounds like you know what I meant.
The post credits scene is an ominous sequel setup though yeah. I'm not sure I like it being there, or at least they could have perhaps done it a bit better.
