Are the images even ingame yet or is this just another clickbait here? Played so many patches and never could leave the dungeon.
I think that you should at least read the thread before asking questions like that, this has been said a lot of times already. What we are all playing is a test to improve core mechanics, specifically the ones in the dungeon. Those are images that will be, and should already be, in the complete game.
And as the creator said:
"I aim to finish the Dungeon Test around very late April or middle of May, then I'll begin to test Alpha version in May or June. Alpha has storyline, quest system, town, new NPCs and adventurers, and many events outside of Dungeon Test. And, of course, many erotic events as well!"
