Spoiler Free Walkthrough :)

(The choices mentioned are the only ones that matters)

If you were stuck on finding that one ending (I don't know why I designed it like that).

Rooftop Dwellers have 5 Endings, it is recommended to get all the other endings before the last one.

Ending 1: 

• "Look through the area more"

Ending 2:

• "Leave the area."

Ending  3:

• "..Go home and sleep?"
• "Go rest..."

Ending 4 (The godforsaken ending):

• "Chants daily ritual."
• "Go to the scene itself" or "Search it up online"
• "Don't check"
• "Look for side treasure!"
• "...Act"

Ending 5:

• "Go back home"
• "Chants daily ritual" or "Slumber once more"
• "Search it up online" or "Go to the scene itself" or "Go home.. and continue the work.."
• "Head in to possible cool secret hideout"
• "Check time" or "Don't check time"
• "Go and explore" or  "Chat Mello first"
• "Look for side treasure!" or  "..FIND 'THE TREASURE' !!"
• "Drop the act."

Alternatively, you can just do the same choices as Ending 4 and just pick "Drop the act." instead.
