好玩喵，属于是断断续续就玩完了喵，难度适中，提示也很有意思。

This game has a surprising amount of depth despite the simple mechanics. I liked the music, and there's plenty of content here. I beat the game 100% and enjoyed the later levels a ton.

clever puzzles and headscratching logic.

There's a real lack of level distribution. More specifically, for schoolchildren. If there were a distribution for elementary school, those who know addition and subtraction, and then, in ascending order, multiplication and division

I was about to give up and refund this when I saw world 8's gimmick, thinking it would just be a generic sokoban game from there. It was not. Incredible game with so much depth, leaves no rooom for disappointment. My only complaint is about how hard final exam is. Maybe I just fluked my way through the whole game.

引入的機制有趣，題目難度較低。 題目整體品質還可以，遊玩過程中僅遇到個位數的題目存在預期外的解法。 遊玩前有點擔心後續謎題重心放在純比拚計算，不過很少有這類型的題目，即使是偏計算的題目本身也是因為存在有趣的計算過程才放在遊戲中，遊戲過程中獲得了許多驚喜。 好的部分說完，談談我不太喜歡的部分。 首先，以遊戲體量而言，價格明顯偏高，不過看附錄似乎有後續增加題目的打算。 其次，相似的題面但迥異的解法是有趣的設計，但這款遊戲相似的題面解法通常沒有差異大到能讓我耳目一新，比如 [spoiler] 9-26(顛倒)&9-27(顛倒) [/spoiler]。類似地，有些伎倆重複出現也讓我有點審美疲勞， 最後，選關與關卡排布導致了流程順序錯位的問題。關卡的解鎖方式導致了玩家可能先打了進階關才打教學關或是先打同類型難關再打簡單關的情況（應該是關卡排布失誤的問題，因為明顯可以透過調整關卡位置控制解鎖順序避免），我在遊戲流程碰到了好幾次。 整體而言，是個還不錯的遊戲，但由於定價問題，僅建議折扣時入手。

Very cool, similar to Maxwell's puzzling demon and also just as good!
