Quoted from Squeakman:BINGO!!!! I love Maiden, but all I see is a mashup rip off of 90's williams games put together. I have played it a bunch and its a good game and doesn't shoot anything like TZ, but dame those flippers are exactly set up like TZ right down to holding the flipper up to make a tight shot more open. Its also got a little Congo pop bumper vibe going on also, and surprise, surprise its been said that the Volcano shot on Congo is one of Elwins all time favorite shots in pinball.
Congo was not the first machine to have a ramp shot through the pops, FYI. All machines borrow design ideas.
