As normal, it's a good idea to do a console reset here to skip the cutscene.

Movements:

• These are the optimal movement patterns for the Muggshot bossfight

Alternative last layer: Chandelier Jump

• This is a way to speed up the last layer by jumping on the chandelier in the center and hitting the mirrors from there, rather than jumping around on all of the spire jumps.

For the last mirror, as normal, you can load the game or use the map to save the time of the final cutscene.

Of course, pan over and X spam to get into the next world.
