Too much 'story elements' introduced in too short span of a time.
Too little interaction with those elements which are introduced.
Too little information about key points.
Add the fact that there sometimes is no choice in areas in which one would expect, and this makes an image of a creator, who just dumps everything he can think of - including kitchen sink - and then discards and removes those ideas as rapidly as they were introduced into the story.
Too much in too short span of a time?
You got atm 9 Updates, each Update is one Day, I dont think its to much informations, I started slow to show you the characters and every character you see again, mc returns to the school too, so think maybe that week 1 was more a intro.
What interaction you want? its not a sandbox game, that you can speak with everyone and grind love/desire points to get actions at night.
there are alot infos about the key points, oracle, max, mc, in d10 you get infos about the prophecy, more from mc life, heaven, hell and and and.
Yeah maybe its not your style, maybe you dont like it or you have different views from a Visual Novel,
I do what I can and I have have many Fans they like what I do.
I love OP Characters in Animes like Momonga, he is the best in my eyes and I hope he destroys everything ^^
and now you can say, no I dont like him, he kills to much ppl, yeah thats your view and thats your right to have a different view.
Maybe you will like it at the end of maou-sama
