I don't know what's up with Day 6 - Petra Theos, but, to me, it seems like this game is kinda unfinished cause:
1. When I clicked on the strange rock and tried going back to the house, I thought of letting myself get captured by the floating dark humanoid figure that chases the player during that sequence. When the floating dark figure got to me, it didn't do anything at all and just basically walked into me without any new screen popping up or any indication of the figure "capturing" me.
2. There's no way to move, interact, or advance in that area sequence with the white void and the two rocks. It just stays like that for seemingly forever, and I've seen some peeps down in the comment section that have gone through this same experience as well.
So, again, not sure what's going on here, but I hope that this game gets updated or fixed in the end. If not, then I guess I can live with that reality as well.
