Alright, so the final floor (F6: Halls of Oblivion) is currently bugged in that Zhang doesn't appear. To fix this (if you have RM Ace), go to her event near Cass and delete the second page. I used the debug menu to get to her while testing the final floor in the last hour of the contest's run, and in my hurry to upload forgot to fix her. Sorry. :<
My plans for v1.1, to come out in a day or two, are to turn the sixth floor into a proper dungeon, rebalance Glorious Herald and Vampire a bit, add some optional bosses on the last floor to get nice gear/the final four weapons, and generally improve the mapping of the entire game.
Any saves on F5 or higher (if you're on F6, just go back up to F5 and save) will be compatible with v1.1. I will NOT be adding new treasure or anything to floors 1-5, only making aesthetic changes.
If you have any suggestions as to what else to work on, let me know!
