Evaluation

The Book of Hiro launched on September 8, 2023 as a complete 7-chapter story experience. The pre-launch announcement explicitly described the release version as containing "a complete story across 7 chapters." There are no DLC listings, no season pass, and no developer communications announcing any planned post-launch content additions. Following launch, the developer issued a feature patch on September 13, 2023 and a bug fix notice on September 10, 2023 — both focused purely on stability and polish rather than new content. The most recent developer communication in the news history dates to September 13, 2023, and nothing in that post or any subsequent communication suggests additional content is in development. The game appears to have shipped as a self-contained, finished product with no post-launch content cycle.

About this game

“The Book of Hiro” is a 3D visual puzzle game developed by two independent developers. Players help Hero embark on an adventure to the palace, using illusions and perspective to solve puzzles and explore the magical world in this book.

[Innovative Visual Puzzles]

The game features innovative visual puzzles that are imaginative and visually stunning. The innovative visual illusion finding gameplay involves moving the viewing angle, clicking, and other operations to find the hidden “key” pattern in the picture. Each puzzle solved can advance the plot and provide a unique gaming experience and visual impact.

[Vivid 3D Graphics]

The game features a simple and fresh 3D low-poly style that is full of childlike innocence while meticulously depicting the different scenes in the story. The game’s soothing and distant music complements the graphics to create a mysterious visual pop-up book.

[Challenging Gameplay]

The game features shiny gold coins, ordinary keys, hammers, gears, and other objects that are common but difficult to find due to the game’s unusual mechanics. Players must make bold guesses and not be fooled by seemingly unrelated images. They must carefully observe and remember that what they see is not necessarily what they get!

[Intriguing Storyline]

The game features an energetic and art-inspired storybook style. Behind the seemingly ordinary protagonist’s travel story is a hidden plot and an extraordinary experience. The game includes a main storyline and hidden endings waiting for you to explore.
