"A living nightmare!" "It messes with your mind!" "Like IKEA on acid!" - just some of the visitor reaction to It Felt Like A Kiss.
IFALK is a spooky interactive theatre experience that unfolds across five floors of a deserted office building. Some say it's like stumbling across a derelict fairground attraction only to discover that it's still haunted.
Made by filmmaker Adam Curtis and Punchdrunk theatre maker Felix Barrett, it's set to an original score by Damon Albarn.
It Felt Like A Kiss runs every day except Mondays until Sun 19 July.
