This is a puzzle game like a mathematical book, based on logic and deduction. In this game, you don't need to beat the level, but need to prove it is beatable. Your goal is not to win, but to prove you can win.

About
This is a puzzle game based on logic and deduction. In this game, you can learn and understand a brand new deduction system, and then take the axioms and rules of deduction as tools, to prove the propositions by entering the code.
Features:
Understand the axioms and rules of deduction (just like when you are reading a mathematical book)
Enter the code and prove the proposition (just like when you are solving a math problem)
"Q.E.D.", "Eureka!", and get into the next loop
Elements which might be frustrating:
No good artwork. (That's less important than the other three)
Amounts of text to read, and it requires a little comprehension of math. (Playing this game is virtually like reading a math book)
The only way to create a new proof step is entering the right code, which is not the core of the game essentially. (It's due to my limited programming ability)
No custom-corollary function. Only the axioms and rules of deduction are available. (Welcome to the CLASSIC deduction system)
If all of them are okay for you, then this game may be suitable for you.
FAQs:
Q: Which players are the game mainly for?
A: If you have some experience of reading math books and you are interested in logic, this game may be the one you like.
Q: Is it a hard game?
A: At the first, the difficulty of this game are mainly about the understanding the rules, and it's easy to work out the puzzle. But the problem will become very hard if you keep playing. Anyway, reading and comprehending themselves will form a part of difficulty.
Q: Are you inspired by something when designing this game?
A: This game is inspired by mathematical logic, mainly about natural deduction of statement calculus and first-order predicate calculus.
Q: How long does it take to beat the game?
A: About 20~40 hours.
Q: Is there any difference between this game and a mathematical exercise book?
A: Nothing. And I just let it be. If some players mind that, it's fine by me to use "the executable file" or "the exercise book" while talking with them, instead of "this game".

我最喜欢的视觉小说
非常好玩,题目难度较高而不至于一头雾水,黑底的讲解非常详细,然后后来又发现了一些问题特意回去验证,让人回味无穷 建议是设置如果明显一点,然后放在一起会更好;括号匹配的高亮也可以更加明显一点
刚到第五章写代码写的头疼且卡关想给差评,熟悉了思路一路打完456章还是很爽的。 论证中的一些重复操作敲起来是真麻烦啊

还是非常推荐的,劝退点在demo中已经很明显了,但是如果你喜欢你就会觉得物所超值。 /这些题目的难度真是不当人,甚至连例题都没有,不看攻略一道题就能卡几小时。/
目前只玩到前兩章,算有意思的遊戲。但就像其他評論說的一樣,操作方式真的有待改進。
上班写代码,下班也写代码
可以,题目做起来很爽,我专门写了个python程序来输出我那些小工具,这导致我的步骤有时候有点繁琐。
重温了一下这款游戏,早在策划阶段本人就参与过测试与意见,同作为游戏开发者表示真的很难想象作者在开发这样一部作品时是拥有了怎样的勇气——而发售后的结果也完全超出了我个人的预期,可以说zqh真的是独立游戏界的一位传奇人物了。
最好增加一个自定义推理规则的功能,很多操作是在反复用之前用过的操作,很麻烦,开启创意工坊
比较看人,游戏本身很有想法,感兴趣的可以试一试,现在也逐渐在更新游戏解决交互上的一些问题
