The scene in that screenshot takes place on Thursday, April 28th. Could be an excursion into the same dungeon but, again, the dates are all over the place so it's hard to tell too much from them right now.
Well, the initial trailer shows the same room as in the screenshot I linked, except it's 4/11, The protagonist is alone (as evident by the UI), and the enemy placement is different. In the trailer,. he zooms on by to the open doors with nothing in his way. In the aforementioned screenshot, the doors are closed, and an enemy is in the way.
We can't tell the date of the screenshot on the website. But there's the similar scene of them jumping over the chandeliers which shows a 4/25 date and a fully party on the website. This same shot in the trailer shows a 4/11 date and only one party member. Which suggests that the hallway screenshot is also on 4/25
