Most of the game takes place in the real world, where the player navigates real-time 3D environments using the DS's D-Pad and Touch Screen.

The player can switch to the TS Menu at any time, where they can play the cursed game, read e-mail messages, and load a previous save file.

In the cursed game, which only uses the top DS screen, the player controls a 2D 8-bit RPG that provides clues to the current situations and can, in some cases, advance the story.

[4] Partway into the game, the player will encounter Regrets (ルグレ, Rugure), zombie-like spirits that roam the area in exploration mode.

[5][6] Regrets take several roles in the game, from standing guard at stationary posts to actively chasing (or attempting to scare) the player.

He confirms a "killer curse" is a real possibility, and sees the nameless game as an opportunity to research its mysteries.

Riko's spirit chases the player out of the hospital after they obtain Yutani's chart and receive a disturbing game update.

[8] On the fifth day, Ooyama finds only one person from Uta-Soft is still alive: Ushio Ikuta, the creative director of the unnamed game.

Ikuta's daughter Asahi, who hated video games (as they kept her father from spending time with the family), came home to find the bloody scene.

[8] On the sixth day, Ooyama explains that Ikuta continued to work on the cancelled game after his wife's death, angering Asahi into running away from home.

They learn Asahi is the true source of the game's curse, having committed suicide by jumping from the top of the lighthouse.

The player heads for the nearby cliff, (depicted many times in the cursed game,) to reach Asahi before daybreak, in 3 minutes.

After talking with Riko, Odaka, and the three missing Uta-Soft employees, the player speaks to Yutani, the curse's first victim.

Tomoka's spirit appears through the game, telling Asahi she is sad her daughter died, and closed her heart.
