Complex personal interactions. NPCs have a sophisticated behavioural system that controls their actions, which meshes with a full dialogue-tree system. Talk to NPCs at different times in different circumstances to get clues or help. It goes very, very deep.
Complex object interactions. Almost every object can be interacted with in some way. Smash bushes, install headlamps in your boat, put things in boxes, or light furniture on fire. Many items can be used in different ways or combined as you gain knowledge.
Fight Carefully. Fight on land or at sea with a variety of weapons and techniques. There is a catch however: if enough people are killed, friend or enemy, the goddess will reset the timeloop. So measure your violence carefully, and know that human life is fragile.
World generation. Each time you go back to day 1, the world geography and layout will change. The main characters in the story are fixed, but a different subset of other people will be chosen each time. Each time the world generates, it's like an alternate timeline that might have existed.
Purgatory. Behind everything lies a mysterious goddess who has enacted the timeloop. Each time you die you visit her realm, where you can purchase certain special items or make other choices that may help or hinder you in your next attempt.
Phone. Your phone is your lifeline and also the main way to progress across multiple attempts. While most of the world is reborn each time you go back in time, anything on your phone stays. Collect files, "CoinCoin" cryptocurrency, and other information to use cumulatively.
