Although I enjoy many works of interactive literature just as well as text adventure puzzlers, I observe that puzzles help language learners to read IF with more focus, care, and investment. Therefore, I find it unfortunate that few East Asian visual novels include puzzles. Those that do tend to limit themselves to instant death by wrong choice. The Poisoned Soup is a rare piece in that the fluently bilingual author is well-read in a variety of IF genres. These range from parser-based puzzle games, to parser-based literature, to choice-based (and basically linear) East Asian visual novels.(Spoiler - click to show) Steven Dong intentionally makes it difficult to select all the right choices in the first play-through. However, wrong choices don't usually lead to instant death without clear warnings. Rather, most wrong choices cause trauma to the PC. As I made progress in the game/work, Dong's method caused, in me at least, a sense of desperation and increasing cautiousness, as well as personal investment in the PC's lot.
I would have to say that this is currently my second favorite Mandarin game after 逃出去 | Escape.
