Emberdeep

Emberdeep is a first-person maze crawler. Every floor is a freshly generated labyrinth, your torch is always burning down, and things in the dark are listening. Find three shards to break the floor's seal, follow the chime to the way down, and see how deep you can get.

Five depths

The halls change as you descend: the Old Stonework, the Mossgrown Halls, the Frostvault, the Cinder Warrens and the Humming Rooms, each with its own stone, light and moisture. Down there you'll meet pale statues that only move when you look away, blue wisps that drink your flame, and shades that hunt by sight.

Between runs

Sanctuaries are safe: "Nothing can follow you here." The Keeper tends a fire that "remembers you". Spend the gems you bring back on permanent upgrades: more hearts, a slower-burning torch, better lungs, extra flash bombs, faster boots. Ilse the Mapmaker can mark the shards on your map, and Brakk, a wounded delver, has tips and a gift.

Play with friends

Click Host for friends and send the invite link. Everyone explores the same maze and sees each other, with no server: browsers connect directly over WebRTC. There's text chat, push-to-talk or open-mic voice that can fade with distance and muffle behind walls, and an optional, unsettling mimic: a creature that wears a friend's look and name tag and plays back clips of their voice. The host can turn it off.

How it's made

The whole game is one index.html with Three.js bundled inline, so it needs no network to play solo. Walls, floors and lighting are generated from code, with quality levels that adapt to your device. An earlier hand-written WebGL2 renderer is kept in the repo as a fallback.

Each floor

1. Find 3 shards. They break the floor's seal.
2. Follow the chime. Once the seal is broken, the chime turns low and warm and leads you to the way down.
3. Some floors have a locked gate: its key is somewhere on your side.

Your resources

• Hearts: you start with 3. Red heart pickups restore one.
• Torch fuel drains constantly. Flasks of oil refill it. When it runs out, it's dark, and creatures can smell you from much farther away.
• Stamina drains while you sprint. Run it dry and you're winded until it recovers.
• Flash bombs (E) drive creatures off.
• Gems are your currency for upgrades. Some walls are false: slipping through one can reveal a hidden cache of 8 gems.

Creatures and traps

• Pale statues only move when you look away. Keep your eyes on them and back off.
• Blue wisps don't bite. They drink your torch, which is worse.
• Shades lose interest if you break their line of sight twice.
• Spike plates: time them, or clear them with a running jump (Space). Don't stop to think on one.

Upgrades (from the Keeper)

Upgrade	Effect	Cost in gems
Vitality	One more heart	15 / 30 / 50
Lamp oil	Torch burns 15% slower	10 / 20 / 35
Deep lungs	Sprinting costs 20% less stamina	10 / 20 / 35
Bandolier	Start every run with one more flash bomb	12 / 24 / 40
Swift boots	Move 6% faster	15 / 35

Upgrades are permanent: they carry over to every new run.

Tips

• Carry your torch fuel like a health bar. Pick up every oil flask, and buy Lamp oil early.
• Ask Ilse to mark the shards and the way down when you meet her: it saves a lot of fuel.
• Hold a flash bomb in reserve for a corner you can't back out of.
• If the dark is too dark, [ and ] change the brightness.
• Runs can be started from a typed seed, so friends can try the same maze.
