一款教「对比论证法」的拖曳游戏，三关共 36 分。由一位华文老师与 AI 对话做成，不需要任何编程基础。
A drag-and-drop game that teaches 对比论证法 across three levels and 36 marks — built by a Chinese Language teacher in conversation with AI, with no coding background.
给学生的两句话：请在 SLS 里作答，不要另开分页，否则 SLS 无法记录分数；三关做完会出现登顶画面，请自行截图交到 SLS。
Two things students need to know: answer inside SLS rather than in a new tab, or the score cannot be recorded; and screenshot the summit screen at the end to submit as proof.
三条路径没有难易高下之分，也不必按顺序走。请按自己的专业发展目标选一条，每条都能独立完成。
The three paths aren’t ranked and don’t run in sequence — pick whichever matches your own goal. Each one stands on its own.

选成 Text/Media 是最容易犯、也最难发现的错：游戏照样打得开，学生照样三关做到底，但分数一个都不会记录，教师后台永远是空的 —— 而这件事要等到你去看成绩时才会发现。这是作者自己踩过的坑，一个班的分数。
Choosing Text/Media is the easy mistake, and the hard one to notice: the game still opens, students still play all three levels through, but not a single mark is recorded and the gradebook stays empty — which you only discover when you go looking for the marks. The author made exactly this mistake, and it cost a class.
另外，Maximum Marks 要设成 36（开场画面显示的满分）。留在预设的 0，分数送出了也显示不出来。官方说明：SLS Teacher User Guide。
Also set Maximum Marks to 36, the number on the opening screen — left at the default 0, the score is sent but never shown. Official reference: SLS Teacher User Guide.
