Those arid cliffs are the canyons, the only part of the overworld you'll probably see. Once there, the sun will be your main concern. Shadows are scarce, and your only allies will be the birds. Using them to get to the other side of the canyon will be your main objective in this time limited race against the clock.
Getting outside is a challenge, but you'll probably need to get out during your journey. Not every cave gets you deeper, sometimes you need to think outside the box to go deeper!
About future content:
-We finally launched, and we are deploying bugfixes since then.
-The main goal is reworking a little the signs and feedbacks of the possession mechanics.
-Some asked about an English voice acted version, we will probably get a voice actor later, once we fixed most of the bugs reported during the feedback phase.
Thanks for all your support everyone!
