I believe if you're in the recollection room and there's a pigeon, that's the end of the update so far to my knowledge. I just finished to that point as well and since I can't interact with that swirling black mass to leave I'm assuming that's the end of the current version.
I think honestly what I'd really prefer & like to see is some better map expansions and an expansion for more free roam. Like, I don't think it's necessary to lock the player out of the swimming/ gym school area for every day only allowing access to the gym if it's Wednesday -- you'd think that the swim club, basketball clubs would at least be practicing so I'd argue these areas should be opened up. The overworld in general for that matter should be opened up.
If the hint tells me that Asuna is at her house for that matter as another example why the map should be more open to free roam, then I should be able to exit whatever map I happen to be on at that time and be able to visit the rich/ upper class district of the map and scope around.
Regarding to FOG, I should be able to access/ log in & log out at my discresion without it being left for the end of the day to close out the day, I want that to be free roam accessible and the day shouldn't end unless & until I decide that I want it to by interacting with the bed. Interacting with Kirito's bed should give two options, access FOG & Sleep till morning.
I know this game is still in a very early stage & all that jazz but I hope that's what the Dev does in future updates. I have always heavily disliked forced linear story telling restricting access to free roam forcing a focus on the main story. I don't mind it, but, Asuna is not the only character and it's very clear that Asuna is not the only girl being corrupted. So, more attention to some side events would also be nice.
