I recently got killed on the down stair, and I happened to touch on the stair tile, and it took me down to the next level (level 3 I think). The little guy reappeared, and I played on as some sort of ghost. I could only see one tile in any direction and could not use inventory items. However I could walk around and defeat monsters by touching them directly (no quickslot for fighting was there anymore). The monsters could not see me, and did not attack me when I hit them. I went down to the Goo and killed him, and then went to the shop on level 6, but I couldn't buy anything. At that point I quit.
Anybody else experience life after death in PD?
