I think you drank a chaos potion. It has a different effect depending on what you do with it: drink it, throw it at a monster or throw it against a wall.
i see. and i'm assuming drinking it causes it do give you poison, burning, etc.. ngl i'll probably never see that potion again because i died and i was really deep in (forgot to record how far) wait is there a way to tell how deep your past runs were?
There is no way to read that info BUT next version will have a "death" screen where you can read info about the run, your inventory and some statistics.
