The Plucky Squire

Story-related; cannot be missed.

This unlocks in Chapter 9 after completing the third and final stealth section where you play as Pip. You move with the beat similar to Crypt of the Necrodancer, and so do enemies. You need to stay out of their sightline and make it through each room to the other side, pressing switches and levers when needed to get through. Rather than trying to press directions on the beat, you can just hold the thumbstick the direction you want to go and you'll automatically move with the beat. This makes it easier than trying to time all your button presses.
