【Game Introduction】
■ Navigating taboo explorations and life-or-death dialogue confrontations
Left: Burglary is a crime. If caught, it could lead to fatal consequences.
Right: Everyone has one or two things they don't want others to know about, right?
The game alternates between two types of gameplay: exploration via point-and-click investigation in low-poly 360° backgrounds (burglary), and option-driven visual novel-style dialogues with Live2D characters.
The story is set in December 1999 at "Tokoyo Building," a dilapidated indoor amusement park rumored to be where people vanish without a trace. The protagonist, Akira, who lost his memory and stumbled into Tokoyo Building, is caught by the owner, Yano, while attempting a burglary. Forced to stay, he becomes an employee living within the park. However, his colleagues are all dangerous individuals. Angering them could have dire consequences. Moreover, escaping this building seems far from easy...
Use your skilled lockpicking abilities to sneak into their private rooms, uncover their "secrets," and find clues that might help you survive.
Left: The employees don't seem to get along very well either...
Right: Without knowing someone, you can't tell what might anger them. However, knowing too much might also raise their suspicion...
During dialogue sequences, other characters' reactions change based on the player's choices. Even slightly offending someone can lead to instant death. Powered by Live2D technology, characters seamlessly switch between various expressions during conversations. When multiple characters are present, pay attention to the reactions of those who aren't speaking. These subtle, unspoken emotions allow players to delve deeper into the story's progression.
Understanding your colleagues' secrets means touching upon their individual worries and pains. Beyond Chapter 1 included in the demo, there are more secrets of residents yet to appear waiting to be uncovered. In this strange interaction where death lurks nearby, will Akira manage to escape Tokoyo Building? Even after the game ends, these colleagues will remain in your heart for a long time. We hope this work provides a unique sense of companionship during your solitary nights.
