It has promising plot of an interactive story with Steampunk background, but then the puzzle stops and the plot stuck when I tried to open the Backstage and eliminate the last Agent (it won't open although I had retrieved the key from the Dramatic Man, had captured the woman in the Machine Room, but the case can't never be solved for the fight in the Control Room or the option of capturing Eric or who forgive my awful memories of the character's name is always reopened although I had win from him ^^;)
