Another novel-accompanying mini script by the author of 《桐花中路私立协济医院怪谈》, 《无形之刃》is similar in having very little text, yet a lot to analyse.
The structure and gameplay flow might feel familiar, too — though some twists are visible quite early, meaning that players might have to ‘play along’ to reach the intended false conclusion, before then overturning it.
While not as cleanly concise as 《桐花中路》, the script does manage to add some character and thematic depth, which I consider a fair trade-off. While not a must-play, it’s solid enough for play-at-home purposes. (I bought it off the official Taobao shop, and we self-DMed.)
Perhaps in a reflection of its novel-related origins, the final case explanation comes with additional reading and explanation of the thematic concerns. Much of it isn’t strictly necessary to understand the solution (which players would hopefully have arrived at themselves, anyway), but can be an interesting read for players who are thus inclined.
Try if you like: An incredibly friendly reading:solving ratio; a substantial case-solving experience in about four hours; close reading; a thematic focus on contemporary societal issues.
Not recommended for: Players who don’t enjoy having to analyse how their script was written.
