Otherworld Philadelphia [Immersive Art]OtherworldEscape roomOther This is NOT an escape room. It’s a massive art installation with a narrative through line, and does contain a puzzle. Once you enter, you have unlimited time to explore the dozens of rooms. It’s clear many of the visitors have no idea there is a puzzle element to the installation. It can be enjoyed without spending a single moment following the storyline or searching for the the 4 clues you need.
