    有时候,让牌组变强的方法不是继续往里塞卡牌,而是勇敢地说一句:“这张先不要啦!”🃏✋现在来到商店后,我可以花费 100 枚金币💰打开完整牌组,从中选择一张卡牌移除🗑️。选中的卡牌还会再次展示出来,请你确认以后才真正离开牌组✅,免得手一滑把重要卡牌弄丢。移除卡牌看起来像是少了一份力量,其实能让牌组变得更加集中🎯。用不到的卡牌少一些,真正关键的攻击⚔️、防御🛡️和恢复❤️牌,就更容易在需要的时候被抽到。当然,金币既可以买商品🛒,也能用来整理牌组🃏。是带走一件眼前的新宝贝✨,还是花钱告别一张总在关键时刻跑出来捣乱的牌?🤔 唔……有些分别,果然也是为了下一次更好的相遇嘛!💫Sometimes, the best way to make your deck stronger isn’t adding more cards, but bravely saying, “Not this one for now!” 🃏✋Once I arrive at the shop, I can spend 100 gold 💰 to open my full deck and choose one card to remove 🗑️. The selected card will be shown again for confirmation before it actually leaves the deck ✅, so I won’t accidentally lose an important card with one wrong click.Removing a card may look like losing a little bit of power, but it actually makes the deck more focused 🎯. With fewer cards I don’t need, the truly important attack ⚔️, defense 🛡️, and recovery ❤️ cards are more likely to appear when I need them.Of course, gold can be used both to buy items 🛒 and to tidy up the deck 🃏. Should I take home a shiny new treasure ✨, or spend some gold to say goodbye to a card that always seems to show up at the worst possible moment? 🤔 Hmm… I guess some goodbyes really are meant to make the next reunion even better! 💫

    我的药水栏终于知道什么叫“装不下”啦!🧪🎒行囊里的药水栏一共有五个位置🧪🧪🧪🧪🧪。获得新的字母药水时,它会优先找到空位乖乖放进去,不会覆盖已经收集到的药水。要是五个格子全部装满,药水栏还会摇晃一下💫,提醒我们真的塞不下啦。如果在宝箱房又找到了新药水🎁🧪,游戏不会让奖励直接消失,而是打开一个替换窗口🔄,把目前携带的药水全部展示出来。只要选择一瓶暂时不需要的药水移除❌,就能腾出位置,收下刚刚找到的新字母🔤✨。五个位置听起来不少,可字母怪足足有二十六种🔤。是留下常见字母的药水,还是专门为危险技能准备几瓶稀有字母,就得认真取舍了🤔。看来整理书包🎒和整理牌组🃏一样,都是冒险中的重要功课呀!✨My potion bag finally knows what “no room left” really means! 🧪🎒There are five slots in the potion section of the inventory 🧪🧪🧪🧪🧪. When you obtain a new letter potion, it will always look for an empty slot and neatly place it there, without replacing any potions you’ve already collected. If all five slots are full, the potion bar will shake a little 💫 to remind us that there’s really no room left!If you find another new potion in a treasure room 🎁🧪, the game won’t simply let the reward disappear. Instead, a replacement window 🔄 will open and show all the potions you’re currently carrying. Just choose one potion you don’t need for the moment and remove it ❌ to make room for the new letter you’ve just found 🔤✨.Five slots may sound like plenty, but there are a total of twenty-six letter monsters 🔤. Should we keep potions with common letters, or save a few rare letters specifically for dangerous skills? That’s something we’ll have to think carefully about 🤔. Looks like organizing your backpack 🎒 is just as important as organizing your deck 🃏 on an adventure! ✨

    轮到谁行动,现在终于一眼就能看清楚啦!👀✨每当新的玩家回合开始,画面上都会出现“玩家回合”🎮和当前的回合数🔢;轮到字母怪行动时,提示则会切换成醒目的“敌人回合”👾⚔️。这些文字会停留几秒再自动收起,既能提醒我们当前阶段,也不会一直挡住战场。轮到我时,能量会重新恢复⚡,五张新的卡牌也会来到手中🃏🃏🃏🃏🃏。等这一回合的安排完成,按下“结束回合”⏭️,剩余手牌就会进入弃牌堆🗑️,接下来便要看看字母怪准备使出什么招式了👀👾。等怪物全部行动完毕💥,战斗又会回到我的回合🔄。出牌🃏、结束⏭️、观察敌人👾,再重新制定计划🧠——现在每一步都有了清楚的节奏。可别看到新卡牌就急着往外丢,先确认现在到底是谁的回合呀!😎Whose turn is it? Now you can tell at a glance! 👀✨Whenever a new player turn begins, “Player Turn” 🎮 and the current turn number 🔢 will appear on screen. When it’s time for the letter monsters to act, the prompt switches to a clear and eye-catching “Enemy Turn” 👾⚔️. These messages stay on screen for a few seconds before automatically disappearing, reminding us which phase we’re in without blocking the battlefield the whole time.When it’s my turn, my energy will refill ⚡, and five new cards will come into my hand 🃏🃏🃏🃏🃏. Once I’ve finished planning for the turn, I can press “End Turn” ⏭️, and any remaining cards in my hand will move to the discard pile 🗑️. Then, it’s time to see what moves the letter monsters have planned 👀👾.Once all the monsters have finished their actions 💥, the battle comes back to my turn 🔄. Play cards 🃏, end the turn ⏭️, watch the enemies 👾, then come up with a new plan 🧠—now every step has a clear rhythm. So don’t get too excited and throw out those new cards right away. Make sure you check whose turn it is first! 😎

    字母怪下一步想做什么,现在藏不住啦!👀🔤每只字母怪都会提前显示自己的行动意图。⚔️ 比如 A 会发动攻击类的“背水一战”,C 会用“坚韧”增加防御,T 则会通过“鼓舞”获得多种增益。✨ 把鼠标移到对应的字母或意图上,就能看到技能名称和具体说明。🔍怪物身上的状态图标也可以查看详细说明了。📖 遇到不熟悉的增益或减益时,不用再对着小图标猜半天,只要把鼠标放上去,就能弄清楚这个效果会怎样影响接下来的战斗。💡先读懂怪物的计划,再决定该出攻击牌、叠护盾,还是用字母药水封住最危险的那一个——这才是聪明的战斗方式!🧠⚡️ 哼,既然它们敢把计划写在脸上,我当然就要好好利用啦。😏✨You can’t hide what those Letter Monsters are planning next anymore! 👀🔤Each Letter Monster will now reveal its intended action in advance. ⚔️ For example, A can use the attack skill “Last Stand,” C can use “Tenacity” to increase its defense, while T can use “Inspire” to gain multiple buffs. ✨ Hover over the corresponding letter or intent to see the skill name and detailed description. 🔍You can also check the detailed descriptions of the status icons on monsters. 📖 When you encounter an unfamiliar buff or debuff, there’s no need to stare at the tiny icon and guess what it means. Just hover over it to find out exactly how the effect will influence the upcoming battle. 💡Read the monsters’ plans first, then decide whether to play an attack card, stack up your shield, or use a Letter Potion to seal away the most dangerous one — that’s the smart way to fight! 🧠⚡️ Hmph, if they’re bold enough to put their plans right on their faces, of course I’m going to make good use of them. 😏✨

    战斗时,我终于可以随时翻看抽牌堆和弃牌堆啦!🃏✨现在抽牌堆与弃牌堆分别放在两个独立区域,旁边都会显示剩余的卡牌数量。🔢 点击其中一个区域,就能打开对应的卡牌列表,仔细看看里面还放着哪些牌。👀 卡牌当前的词性、升级状态和附加描述也会一起保留下来,不会因为进入牌堆就偷偷变回原样。📖✨每个回合开始时,我会从抽牌堆抽取五张卡牌;🎴 用过或没有保留的卡牌,则会进入弃牌堆。🗑️ 当抽牌堆空掉以后,弃牌堆里的卡牌会重新洗好,再回到抽牌堆等待下一次登场。🔄这样一来,战斗就不只是盯着眼前的手牌啦。👀 想知道关键卡牌还有没有机会抽到,或者刚用掉的牌要等多久才会回来,都可以先打开牌堆确认一下。多看一眼,也许就能提前想好下一个回合的计划!🧠✨During battle, I can finally check my Draw Pile and Discard Pile whenever I want! 🃏✨The Draw Pile and Discard Pile are now placed in two separate areas, with the number of remaining cards clearly displayed beside each one. 🔢 Click either area to open the corresponding card list and take a closer look at what’s still inside. 👀 A card’s current part of speech, upgrade status, and additional description will also be preserved, so it won’t secretly return to its original state just because it entered a pile. 📖✨At the beginning of each turn, I draw five cards from the Draw Pile. 🎴 Cards that have been used or aren’t kept will be moved to the Discard Pile. 🗑️ Once the Draw Pile is empty, the cards in the Discard Pile will be shuffled and returned to the Draw Pile, waiting for their next chance to appear. 🔄With this change, battles are no longer just about watching the cards in my hand. 👀 Want to know whether there’s still a chance to draw that crucial card, or how long it’ll take for a card I just used to come back? Just check the pile first. One quick look might be all it takes to plan ahead for the next turn! 🧠✨
