First endless run and I got to floor 16, felt pretty good but was looking for some more damage at the end. Lost when I encountered an enemy distributing half my health pool (73 hp) in poison every other round. The mace, warding band, and glass belt are a broken combo and then the fish sword was my damage dealer.
Love this game, but like other posts said it did get very repetitive at the end with me attacking 30+ times per turn.
