ERROR143 is a romance visual novel where players develop a relationship with Micah Yujin, a hacker they initially meet through an online competition. The story begins after the protagonist finishes second in a hacking tournament. Unwilling to accept defeat, they access the winner’s computer and leave a message mocking his victory. Micah responds by hacking their computer, beginning a rivalry that gradually develops into something more personal. The game focuses on conversations, player choices, and the consequences of different responses.

From Hacking Rivals to Personal Conversations

Much of the story unfolds through computer interfaces, text messages, and video calls. Micah frequently challenges the protagonist, makes jokes, and attempts to learn more about them. Players can respond with sarcasm, flirt with him, or establish boundaries. These interactions influence the direction of the relationship. The dialogue also reveals details about Micah’s personality, interests, and personal life as the two characters become more familiar with each other.

Choices That Change the Story

ERROR143 uses interactive dialogue rather than action-based gameplay. Players read conversations and select responses at important moments. Certain decisions can change subsequent scenes or determine which ending becomes available.

The main gameplay features include:

•         Dialogue choices that influence the relationship with Micah.
•         Text conversations and voiced video calls.
•         Hacking-themed puzzles and interactive sequences.
•         Character naming and pronoun customization.
•         Three endings in the original base story.
•         Hidden interactions and additional computer content.
•         Extra story chapters that continue the relationship.

How to Play and Reach Different Endings

Players use the mouse to select dialogue options and advance conversations. Some sequences require keyboard input to complete hacking challenges. The main objective is to follow the story and decide how the protagonist responds to Micah’s behavior.

ERROR143 does not contain traditional numbered levels, combat, or exploration challenges. Instead, the narrative progresses through days and conversations. The original story includes a main ending, an unfavorable ending, and a secret proposal ending. Additional chapters extend the relationship beyond the initial events. Players can replay conversations and make different decisions to explore alternative outcomes. Paying attention to dialogue choices is important because certain responses can significantly change how Micah reacts.
