ドトコイ is a simple love adventure game where players read text and make choices to progress through the story. The game recently underwent a major update in August 2020, adding new characters and scenarios.

At first glance, the resolution of the handsome characters may appear low, represented by ■ symbols. However, as the player's favorability with the characters increases, the graphics gradually improve, eventually revealing properly drawn illustrations.

There are a total of 11 characters to pursue in the game, and the difficulty level is relatively low, with each character's route taking around 20 to 30 minutes to complete.

The story revolves around a second-year high school student who starts a new semester at a transfer school. While running along the new commute route with excitement, the protagonist accidentally bumps into a mysterious figure represented by ■, triggering a spell that lowers the resolution of attractive characters.
