Another shower of ideas.
Farm zone have a limit of actions to change schedule.
Timetable (for redundancy)
A chrono effect with morning, noon, afternoon, evening, night and deep night. These bring changes to the zones like appearance of enemies or creatures, change of location of characters or resources or change of generation of resources (activating repeatable events can change the timetable you are in).
Lamps and variants.
Various accessories of which can serve as objects of exploration.
Option to skip the labyrinth (since the game at the start that point does not work and continues to put the screen dark) as a temporary solution.
Analog wrist watch (survivor class).
It is used to skip the time stage, besides being able to check in more detail your stats and other things.
