地图标记服务：值不值得买？
Sky City 的一位 NPC 会售卖"地图标记"——付钱后，把"升级 / Boss / 任意地点"等目标标在地图上，避免迷路。Steam 成就"全标满"也是该服务的内容之一。
- 第一次购买对应成就 Pins in the Map（1 点），较低门槛。
- 购买 5 个付费门则对应 Paying Your Dues。
- 刷齐 5 个地图标记对应 All Mapped Out。
如何识别"未探索出口"
很多玩家卡在"明明有条路，可怎么也找不到"。下面是几个"看地图 + 看场景"的小技巧：
- 地图边缘的虚线 通常代表"未走过的连接"，点过去会切换显示。
- 背景留白 = 还没去过的区域；不要假设"地图上没东西就真的没东西"。
- 磁力核心方向：拿到的引导箭头会指向下一段主线；如果那个方向看起来很偏，往往是"绕路收集"而非"主线最短路"。
- 地面对齐：如果地图上有两个未连岛屿的图标相互挨着，意味着它们之间很可能存在"连接后才会出现"的隐藏过道。
常见视觉线索（屏幕里的小提示）
- 可破坏木箱：木色，有微小裂纹；轻击即可。
- 金属箱 / 铁门：深色、有金属边；需要 下劈 / 蓄力。
- 能力门：颜色与"对应能力"绑定——通常以能力相关的符号或色调提示；拿不到时不要硬试。
- 隐藏墙：和普通墙几乎一样，但有"通风口"或细微裂缝；下劈可破。
- 存档点：小床，靠近自动提示。
- 存档点旁的 NPC：大多数都是带线索的支线，可停下对话。
读地图的两条铁律
- 新连完一座岛，先打开地图看新生成的缝隙。通常会突然出现通往相邻区域的新路，里面可能藏着挑战或升级。
- 找不到目标，先打开地图看是否勾过"未探索"区域。Islets 的隐藏房间常常在地图的"细缝"里，不走到那附近不会显示。

The map-marker service
A Sky City NPC sells map pins: pay to mark a target (upgrade, boss, etc.) so you can find it again. Several achievements tie into this system.
- First pin → Pins in the Map (1 pt).
- Open 5 paid gates → Paying Your Dues.
- Buy 5 map markers → All Mapped Out.
Reading unexplored exits
- Dashed lines on the map edge usually mean a connection you haven't walked yet.
- Empty space = "not visited yet". Don't assume blank equals "nothing here".
- Core arrow points to the next main step; if it looks out of the way, you're being routed through a side collectible.
- Adjacent detached isles often share a post-fusion passage that only opens when both are connected.
Common visual cues
- Wooden crates: light brown, hairline cracks; break with a light attack.
- Metal crates / iron doors: dark with metal trim; need a Plunge.
- Ability gates: colour-coded to the ability they require; don't brute-force them.
- Hidden walls: look almost normal, but have a vent or seam; a Plunge often breaks them.
- Save points: small bed, prompts on approach.
- NPCs near save points: usually worth talking to.
Two map-reading rules
- After each fusion, open the map and check the new seam. It's almost always a fresh shortcut or challenge room.
- Lost? Open the map and look for unexplored regions. Islets' hidden rooms are usually tucked in the map's thin gaps and won't show until you're physically nearby.
