How to Play Knights in the Nightmare
Quick start
Open the tutorial and complete First Steps before starting a new game on Easy or Normal. Practise moving the Wisp, charging a knight’s basic attack and lifting the stylus to release it. Then try dragging a compatible weapon to a knight and using the L/C switches. In the opening battle, keep collecting MP and dodge before charging again.
Controls
Move the stylus on the lower screen to position the Wisp on the upper battlefield. Move onto a knight, hold to charge, aim and lift the stylus to attack. Drag a suitable weapon onto a knight for a skill. Manipulate the on-screen L/C switches to change phase. Holding L or R enters Escape mode, reducing incoming Time damage while preventing normal interaction.
Knights in the Nightmare — About this game
Knights in the Nightmare mixes battlefield planning with stylus dodging. Rather than moving a conventional squad one unit at a time, you steer a Wisp, awaken knights and direct their attack areas while enemies fill the field with projectiles. Basic attacks help gather MP, and suitable weapons enable stronger skills. Law and Chaos phases change available attacks and weapon use. Taking a hit costs precious turn time, so a good plan also needs steady hands and attention to the bullet patterns.
