The dungeon is now, graphicaly speaking, complete.
I don't want to spoil everything so here is a screenshot of Mr. White's hideout.
Apart from the layout, I also finished the boss fight at the end of it. The boss will be using skills and will require some tactical thinking to take down, but it won't be that difficult to take out.
Only thing left to do is to make all the dialogue and some other minor things. If everything goes smoothly, the dungeon should be released next monday.
Also, this version will NOT be compatible with old saves (Unlock will stay, as always) so be sure to finish your playthrough before that.
