We’ll also be taking part in Steam Next Fest next week. Please look forward to it!
This demo lets you experience the first nine scenes of Chapter 1 of The Grade 5B Case Files. Get an early look at how Holmlyn and Watsonia form their team of two, and follow the beginning of their first investigation and deduction as you get a feel for the game’s story atmosphere and mystery-solving rhythm.
The full version will feature a linear chapter-based story structure. The game will have 5 chapters in total, with each chapter taking about 1 hour to play. Chapter 1 will be released for free and can be enjoyed as a complete standalone story. Chapters 2–3 will be released together as DLC, while Chapters 4–5 will be updated later after the earlier chapters are released.
The stories of Chapters 1–3 are planned to arrive this summer!
If you enjoy elementary school everyday life, classic mystery deduction, and stories that uncover the truth step by step from “seemingly ordinary little things,” don’t miss it!
Please add The Grade 5B Case Files to your wishlist and support us!
