i thought this mimic tension room was interesting, i guess i imagined mimics imitating a random object, but the room shows that at least in my game they only show up as water, robes, daggers, silver colored wands, and iron rations. i assume it depends on which square the spawn in.
i have never seen something so odd as a wall of hidden doors. a little odd, only reason i posted was i've never seen anything so weird in my level generations
