The whole point of item costing is so you earn the cool things. Guests wouldn't have earned anything to have all the items, unless they've played non-stop for a while.
I still see the occasional.... thing... sticking out of the wall. It flickers, then disappears as i pass it. Doesnt seem like an intentional obstacle, but great game overall 5/5
@Manuals Thats a little hard to enforce. Usually its not because sham favors the top person, its just that it would waste time for them to go after one person instead of just finishing the rest off. Survival of the fittest.
Dont know if it would be cool, but along with ponylips100's idea, you could earn these 'suicide' emotes as you earn other titles. Magician title makes mouse dissapear in a puff of smoke, Hawk title could make you fly away (but cant be used to cheat ;P) etc, and you would be able to interchange between what you want.
