Shh, Don't Break the Rules!

The author's writing in capital letters is okay. There are no traps in the dungeon rules. The supporting characters other than the protagonist are too brainless, and the protagonist is not very smart. The dungeon is too simple. Looking at the previous description, how difficult do you think it is? The author is advised to read more novels of the same genre that score 8.0-9.5 Points.
