For the first thing I agree with @Doublethree1 and @Yerian, Gekkan-shoujo and Shirobako are both great
Sunday without God really was great, I was so disappointed when I realized that it’d end with some random arc-ending… as for anime like it, I’m not really sure if I know any like that, maybe Shinsekai yori? Doesn’t involve anything about god, but it’s set in a fantasy-like future too (can’t say any more than that tho because spoilers)
A bunch of people on MAL recommend Angel Beats but I guess we got that covered^^
