You know the deal. The only thing is this guide is going to be outdated soon, as Joaco is working on update for this game, so know this guide is for v1.09...

Dream Santy - he goes through hall to your room. Once he is ready to attack, he will knock on your door and white marker will appear on the door. To defend against him just hide under the bed and don't leave it before Santy is gone.

Dream Curi - he has 2 types of attack. He will go out the closet. When his head is near the right edge of the closet, spam flash him to make him leave, Don't hide under the bed, go to hall or window, as he'll instantly kill you. The other attack is constantly rising arms on the edge of the bedroom. Just flash them to make them go down. You can do so under the bed too.

Dream Titi - also has 2 types of attack. He will go from an edge of the room to the center. To prevent death, just go to the opposite side of the room he came from. Once you hide under the bed, he can appear here too. If his eye is glowing, flash him until he leaves. If his eye doesn't glow, don't do it as he'll instantly kill you.

Dream Nick - he goes to your window. If you hear something hitting the window, he is there. Just close the curtain and wait until you hear him leave. You don't need to flash him to defend against him

Demon Toby - same as Santy. No need to explain him.

Demon Ellias - he will kill you if your screen becomes too dark. If he appears in front of you, don't use your flash light, or else he'll take a whole charge of it, which will kill you on max mode and A.C. He will leave eventually, and won't stay to the point you'll die. If he attacks, Curi's arms aren't moving.

Strats time.

Max mode - isn't really hard. Just hide under the bed for the whole night. Once Santy and Toby attack you once and you don't leave the bed, they can't move until you leave it. Wait for Nick to hit your window and defend against him.

A.C.(all challenges) - impossible. If you remember correctly, i said that if you flash Titi when his eyes aren't glowing, he'll instantly kill you. He is guaranteed to have eyes not glowing, and Dark mode challenge makes it impossible to see what eyes he has.

That's all. It's sad that at the moment i'm writing this it's impossible to 100% beat this game, but update is soon, so i don't think it's really THAT sad.
