neat little demo, but i find some bug "0.0.3" if that help ,
(i dont have screenshot/video, sorry)
the slime can glitch the sack where you cant pick it up, but can still put item in it (i did try using the box in sewer, no collision(only lost 1keys)how i dont know ,maybe he try to eat it, the slime or chest)
the thief "dont steal" pop-up can make some item got in the floor/placeholder if too close ,it was the sword and a bag of coins that was on the floor (i got lucky that the key did not or it was an hardlock)
it look like guard can see through placeholder sometime (in armory)
hope this get finish in 1 to 3 years maybe 5
