Started playing Hexen in Doomsday and after some time I got stuck in the Seven Portals realm near the second portal for the Ice world. I'm down where the rising ice pillars are but I can't progress nor go back. The stairs are both too high for me. It's been to long since I last played Hexen to remember if this is intended behaviour and I'm just doing something wrong or is there something amiss with my game?
