I did Whipping and Misshaping and i still couldn't get through the last level because the red button was on the wrong side. not sure if anyone else had this issue still.
Also, on a Candle Stick Keep, the candles looked like they were lit up (blue), yet when a big shadow cat (forget name ><) went inside the light it did not disappear.
You need to talk to one of the knights with the shimmering light to open the gate. Knight is on the right side with a box I believe.
