User Reviews

The game is praised for its engaging, original mystery and strong visuals, with rewarding clue-solving and minimal ads. However, many players report painful difficulty spikes around levels 7–9, plus unhelpful hints and occasional misfeedback where correct answers are marked wrong. Several reviews also note puzzles sometimes lack coherent context, and translation/localization issues. Despite the tough puzzles, fans want more content in English, indicating a promising concept that isn’t consistently polished at higher levels.

The story is absolutely amazing, original, and captivating. My only issue is that some of the solutions don’t make sense in the context of the question. I say this as a 25 year old with her Master’s in Biomedicine. I was confused playing this game more than in my pharmacology class lol
