Does my world actually save, or does it reset every time?

It saves for real, in your browser. DELVE never stores the whole map — the world is generated fresh from a single integer seed every time you load it, and only the tiles you actually changed (broken or placed) are kept as a small list layered back on top after regeneration. Close the tab, come back tomorrow, and every tunnel you dug and every torch you placed is exactly where you left it.

How is DELVE different from Voxel Valley and Riftwarden on this site?

Voxel Valley is a 3D block world you explore and build in, with no combat or crafting progression gating you. Riftwarden is a 2D roguelite where each run is a self-contained gamble — descend between enemy waves, haul ore back, no persistence between runs. DELVE sits between them: a single persistent 2D side-view world (not a fresh run each time) where mining, smelting, crafting better tools, building, day/night survival and a boss fight all feed into each other over as many sessions as you want.

What happens when I die — do I lose my stuff?

You lose a small slice of your currently held ember currency, dropped where you fell — nothing else. Blocks you've placed, ore and bars in your inventory, and every tool you've crafted are always safe. You respawn at your bed if you've placed one, otherwise back at your original spawn point, at full health.

DELVE — Free Browser 2D Mining & Building Sandbox, No Download

DELVE hands you a pickaxe, a torch, and a world nobody has dug into yet. Break dirt and stone, follow ore veins down, and build back up: a workbench, a furnace, a bed to mark home. Every layer down gets harder — your starting pickaxe can only bite so deep, and copper, iron and gold bars smelted at a furnace are what let you craft the next tier of tool and keep going. The world remembers all of it. It isn't a fresh run every time you open the tab; it's the same persistent place, one seed, one save, one dictionary of everything you've changed.

Ten minutes make a full day-night cycle. Daylight on the surface is safe enough; night brings prowlers out of the dark and up to your door. Underground doesn't wait for nightfall — it's permanently dark down there, and it stays that way until you carry light in yourself. Deeper still, past the iron and gold seams, a core chamber waits behind a locked-in ring of bedrock. Craft a root totem from iron and gold bars, carry it down, and use it to wake the Root Warden — a two-phase boss fight that's the closest thing DELVE has to an ending, though nothing stops you from digging past it.

DELVE is PLAY GRID's take on the dig-craft-build-survive genre, built deliberately different from the two nearest games already on this site. Voxel Valley is a 3D block world about open exploration — no combat, no crafting ladder gating your progress. Riftwarden is a 2D roguelite where every run is a self-contained gamble: descend between enemy waves, haul ore home, no world persists between attempts. DELVE is neither — it's one 2D side-view world that stays yours across as many sessions as you want, where the point isn't surviving one clean run, it's slowly turning a hole in the ground into something.

How to play

Move with the left touch zone or arrow keys/WASD; jump with the floating button, Space or Up.
Aim with the right side of the screen (touch) or your mouse cursor (desktop) — anything within reach gets a target box. Hold to mine it, or switch to place mode (the ⛏/🧱 toggle) to build with whatever block is selected in your hotbar.
Your best owned pickaxe is used automatically for mining — no manual re-equip needed after placing blocks.
Open the pack (🎒) to see recipes: some craft anywhere, most need a nearby workbench, smelting always needs a nearby furnace.
Dying only costs a slice of your ember currency. Blocks, ore, bars and tools are always safe.

Things that are actually true in here

The whole map is never stored — it's regenerated from your world's seed every time you load, then your saved edits are replayed on top. That's the entire save file: a seed and a list of changes.
A tool's tier decides what it can break, not what it's called — the starting pickaxe already mines copper; you need to smelt and craft your way to iron/gold tiers for the ore below it.
Underground darkness has nothing to do with the surface's day/night clock. It's permanently dark past a few tiles of depth, day or night, until a torch or your own body-light reaches it.
The daily expedition is a separate, small, date-seeded map — nothing you do there touches your persistent world, and nothing in your persistent world carries into it.

掘光 DELVE 给你一把镐、一支火把，和一个还没人碰过的世界。凿开泥土和石头，顺着矿脉往下走，再往上盖：一个合成台，一座熔炉，一张标记家的床。越往下越难——起手的镐子只能挖到一定深度，只有在熔炉把铜、铁、金矿炼成锭，才能合成下一级工具继续往下走。这个世界会记住这一切。它不是每次打开标签页就重来一局，而是同一个持久的地方，一颗种子，一份存档，一份「你改动过什么」的清单。

十分钟一个完整昼夜。地表白天足够安全；入夜后，游荡的生物会摸到家门口。地下不等天黑——那里永远是暗的，直到你自己把光带下去。再往深处，越过铁矿金矿之后，一间被基岩围死的核心密室等在那里。用铁锭金锭合成一枚唤根图腾带下去，唤醒根须卫士——一场两阶段的 Boss 战，是掘光最接近"结局"的地方，虽然打完之后什么都拦不住你继续往下挖。

掘光是 PLAY GRID 在"挖矿-合成-建造-生存"这个类型上的原创尝试，刻意与站内最接近的两款游戏区分开：Voxel Valley 是一个 3D 方块世界，核心是开放探索——没有战斗，也没有合成阶梯卡着你的进度。Riftwarden 是一款 2D roguelite，每一局都是一次独立的赌局：在波次间下潜、把矿背回家，局与局之间没有世界会留存下来。掘光两者都不是——它是同一个 2D 横版世界，跨多少次会话都还是你的那个世界，重点不是打赢干净的一局，而是慢慢把地上的一个洞变成点什么。

怎么玩

移动用左侧触屏区或方向键/WASD；跳跃用悬浮按钮、空格或上键。
屏幕右侧（触屏）或鼠标光标（桌面端）负责瞄准——伸手可及的范围内会出现目标框。按住开挖，或切到放置模式（⛏/🧱 切换键）用热键栏选中的方块建造。
挖掘会自动使用你拥有的最好的镐——放完方块不需要再手动切回工具。
打开背包（🎒）看配方：有些随地能合成，大多数需要靠近合成台，熔炼永远需要靠近熔炉。
死亡只损失一点余烬币。方块、矿石、金属锭和工具永远不会丢。

这里面是真的东西

整张地图从不整体存储——每次加载都用世界的种子重新生成一遍，再把你存档里的改动清单原样铺回去。存档就是一颗种子加一份改动清单，仅此而已。
工具能挖什么由它的「级别」决定，不是名字——起手的镐子已经能挖铜，铁矿金矿需要先炼锭、合成升级才能挖。
地下的黑暗跟地表的昼夜时钟没有关系。往下走几格之后，不管白天黑夜都是永久黑暗，直到火把或你自身的光照到那里。
每日速掘是一张独立的、按日期播种的小地图——你在那里做的任何事都不会碰到你的持久世界，持久世界里的任何东西也带不进那张图。
