This new update for the "item using exploit". In previous version even you don't have the key item you could unlock the doors without using the item menu. It should be fixed by the new upload. PHEW... Now I can relax.
A new mysterious wardrobe(?) added to the main corridor where the bounty board in it. So... its key item will be in later maps (soon).
Also a new map added with this update; Prison (ehm torture room).
~Did I mention constant lightning effects are improved~ Yay!
