Player Dilemma
Time is of essence in this game. Players are presented with a dilemma in the choices they can make in the day time. As players can only move safely in daylight, players will have to find a good balance between preparation in ensuring their survival at night, and exploration to advance towards their objective. Staying in one place for the day allows the player to harvest more resources, thus increasing their chance of survival at night. Exploring the island allows players to make progress, find rarer resources and possibly find strategic locations to hold their defences at night.
