Bopp File is an intriguing indie adventure game that combines spot-the-difference mechanics with room escape elements. Set in 1998, players take on the role of Benjamin Cooper, who wakes up in his apartment with amnesia. A demon posing as «The Exile» lures Cooper into a trap and demands that he escape within a certain time frame or face death. The game’s eerie atmosphere is enhanced by a mysterious connection to fragments of Comet Hale-Bopp. Moving through looped spaces, players must find anomalies, study the diaries of Cooper and the cult bishop, and uncover the true motives of the demon. The narrative unfolds through the clever tricks used by the demon, creating a tense and aggressive atmosphere. Developed by alu, this unique puzzle game offers an exciting combination of mystery, supernatural elements and challenging gameplay.
