Abstract: Movement control of a player character in a field in a virtual space is performed based on a user's operation input. At least one first type of object is disposed in the field. Lightness for the first type of object is set such that the first type of object is visually recognized even when the field is dark. When the player character satisfies a first condition at a location where one of the at least one first type of object is disposed, lighting is set in the virtual space such that a range in the field including the location is lighter than before the first condition is satisfied.

Abstract: Movement control of a player character in a virtual space is performed based on a user's operation input. When it is determined that an impact has been applied to a first object in the virtual space, the first object, or a second object instead of the first object, is installed on a terrain object related to a location where the impact has been applied to the first object, and lighting is set in the virtual space such that a range around the location where the first or second object is installed is lighter than before the installation.
