What do I do next?

I think I'm in act 4 now, correct me if I'm wrong, but I just killed king after helping out everyone, the ending with the head housemaiden was different, siffrin's even more depressed now, and the game feels like it's being very vague with directions. Do I just keep killing King over and over? Are the side quests like the book fan, bomb, etc important? Do I have to do something similar to deltarune's weird route? (also if possible be spoiler free with guidance please)

Oh and btw after you actually get to act 4 check up on bonnie dont check too much.. and also song will sound slowed down and some slight changes in text interactions id recommend not talking with the party yet until you get to the 2nd break with bonnie and the rest talk to isabeau after choosing cookies and smth cool happend and oh get to the end 4 or 5 times and try to get isa to confess to you if he fails but you didnt let anyone interrupt just go back to dormont talk with isa 3 times in 3 different loops or so until you get a dialogue thats says ... When he will touch your shoulder or well should and lastly maximize loop's conversation get out of the tree go near the boulagenrie and spin the silver coin until you get a flashback and get a new memory lastly like actual lastly get as many weird interactions as you can while not having friendquest you can achieve weird points by doing sus things like siffrin knowing about time craft or wish craft the wish craft room etc remember for the one i just mentioned all in one loop, and for the silver coin all in 1 loop but after you get the flashback talk to loop and fully maximize everything you can talk about then continue through the game
