The map layouts for all 5 floors in adventure mode have been finished! You can view them by either going to the mode's page on the JBM wiki (https://johnsters-baldi-mods.fandom.com/wiki/Adventure_Mode) or you can take a look at them below.

As you can see, some of the things planned to be added to the mod I mentioned in dev. update 8 can be seen here (like the flooded room with the rotating vending machine and the item-o-matic machine).
