Config

The Config (JP: せってい) menu is where the player can modify game settings for Deltarune. It is only accessible through the Dark World menu, and is the rightmost option with the wrench icon.

Master Volume

The Master Volume is a setting that changes the volume of all in-game audio. It can be changed to any even integer percentage between 0% and 100% volume. The default value is 60%.

Controls

The Controls option brings the player to a different sub-menu where all of the controls can be remapped. There are seven different remappable controls followed by an exit option and an option to reset to default bindings.

These are the default bindings:

Function	Key	Switch	PlayStation
DOWN	DOWN Button
RIGHT	RIGHT Button
UP	UP Button
LEFT	LEFT Button
CONFIRM	Z, Enter	A, ZL	X, L2
CANCEL	X, Shift	B	O
MENU	C, Ctrl	X	Triangle

The Controls sub-menu

By default, the left trigger functions as an input for Confirm despite not appearing as such in the menu. It can be used alongside what is chosen in the menu. If the gamepad input for Confirm is manually rebound to its default (without using the "Reset to default" option) the left trigger's functionality goes away, and it cannot be used for Confirm unless it is manually bound to Confirm or the controls are reset to default.

At the start of a Chapter, certain characters may remind of the option to run.

Simplify VFX

Simplify VFX simplifies the game's visual effects, possibly in order to improve performance on computers with less graphical capability, or reduce eye strain/motion sickness. It is off by default.
