Routes

In, there are multiple gameplay routes that can be followed, that lead to an outcome of a route upon successful completion of the run.

The outcome of a run in is determined by two factors:
 * How many bosses have been killed, out of the total number of worlds - 1
 * How many bosses have been spared, out of the total number of worlds - 1

If any route conditions have been met, the player will be set on that specific route, or is otherwise put on the Neutral route. The route chosen changes the final world the player enters.

Neutral
This is the default route. The final zone is Eden (Normal), with a single zone - a boss encounter with the Gate, and a special version of Serif afterwards, which kills the player. Dying after Serif spawns counts as a game completion, and a death.

Pacifist
This route occurs when the player has not executed any bosses, and changes the final world in this route to Eden (Pacifist), which has a single zone. The final boss of this route is Terrable. Defeating her grants an execution choice for the player.

True Pacifist
This subroute occurs when the player has spared Terrable, leading to a unique cutscene and then sends the player to the credits sequence.

False Pacifist
This subroute occurs when the player has executed Terrable, leading to the above cutscene (but without Terra) and then sends the player to the credits sequence.

Genocide
This route occurs when the player has slain every world boss encountered in the route, leading to Eden (Genocide). Genocide cannot be completed without killing the Shopkeeper (Boss), though is still accessible without her death. This world has a normal amount of combat zones, with tougher enemies than other worlds. The final boss of this route is a normal encounter with Serif. Serif can only be defeated with, as per a scripted event and is only obtainable at the end of the fight after every other boss has been slain.
