Periphery Synthetic EP v0.5.1

Functions update

Greetings surveyors!

In my last update I revealed that the EP was feature-complete. Since then I’ve been refining those changes to share. This update introduces several new features and improves the new player experience. Discover and fast travel between destinations, collect ancient artifacts, open secret caches, record your thoughts, and more.

When starting a new game, you’ll find that the tutorial has been simplified. As you explore and interact with the world, you may receive notifications of newly available functions. To access them, you may press Tab or Select while in-game, or access them from the paused menu like before. From here you may read your perceptions or fast travel to any selected destination.

Beware that the perceptions here are simply placeholders. They will be expanded upon in the full release. I’m looking forward to sharing that soon.
