Every time we blink, the game briefly projects a hitbox behind us in order to register touches on scrolls or checkpoint triggers that we may have passed through. By facing backward immediately after the blink, the hitbox is still projected behind our character, but now that we are facing backward, it is projected in the forward movement path instead of the path we just travelled. This is used in three different ways:

  1. Scrolls, Equipment, and Checkpoint triggers can be reached from a two-blink distance, saving a fraction of a second with the forward-projected hitbox.
  2. The forward-projected hitbox can penetrate walls, allowing us to collect scrolls through walls or touch unreachable checkpoint triggers protected behind walls or doors.
  3. Blinking through a checkpoint trigger with EBH means we never register a touch on it, which allows us to avoid touching certain triggers like the ones that initiate boss fights, allowing us to skip two of the bosses in the game.

Key Binding[]

Bind a spare button to Blink as well as Left and Right. Pressing this key while walking will cause you to blink and face the opposite direction simultaneously.

EBH keys have been set on the Gamepad section of this control setup screen. Gamepad users can configure the Keyboard section the same way.
