I did the joker's room and the last puzzle didn't make sense at all. When we called for help, the guy said "I just know the answer but not sure how to get it"
Also really really bad customer service. The girl at front desk gave us attitude from the beginning.
Never come back again. Rather go Escape Game. cheaper and much higher production value.
Ps: I don't work for any escape game company and it was my first time to be here at omescape.
