About the Game
“Apollo Sonata” is a 2D story-driven exploration ADV.
A mysterious urban legend has been spreading. Every night, strange incidents occur on campus—blood flowing from toilets, blackboards covered in garbled writing, a path to the underworld appearing in the sky, and a piano playing by itself on the rooftop… It is said that these are all curses caused by vengeful spirits?!
The adventurous high school girl Juniper organizes a courage-testing event and invites her two friends, Miu and MOMO, to join her.
Are these four famous urban legends real, or is there a hidden truth behind them? And wait—more strange events happen during their adventure…? Follow the girls’ footsteps and uncover the truth yourself!
Multi-Perspective Storytelling: Play as each of the three girls, deeply immerse in their roles, and enjoy delicate psychological depictions.
Light Horror Elements: Explore the mysterious campus at night and witness urban legends and supernatural events firsthand!
Expansive Plot: Experience all perspectives unfold and enjoy the satisfaction of uncovering every foreshadowing!
Exploration & Collection: Even the same items provide different feedback when investigated by different characters, possibly revealing interesting memories along the way.
