There are task prompts. Isn’t there a button in the lower right corner?

However, there are indeed no prompts for some hidden tasks. I personally suggest that when you play it for the first time, you can play it by yourself without modifying it or reading the guide. . . You can play it carefully the second time. After all, having fun in the game is the most important thing.

Regarding the modifier, I have also used it. I modified it with Kingsoft. As you said, HP and EP saving are useless. I guess it is some data in the memory that is modified, which is the cache. Yes, once you turn off the modifier, it will have no effect. You can try it.
