That was really, really good. The bit with the mouse was really pretty neat. The graphics and overall atmosphere were pretty spiffy as well. The only part I didn't like was the face reveal, but everything leading up to that was spectacular. I thought afterward it would have been funny if the rising stinger ended with a goofy face and a derpy noise from the ghost instead. Regardless, it was a great idea, and the buildup to it was really well executed.
