FangVault is a time-attack dungeon platformer I built to be beaten fast and replayed forever. Every level is a sealed vault chamber: find the buried key, race back to the door, and escape before the clock catches you — dodging crushers, fire jets, spikes and six world bosses along the way. Clear all 41 handcrafted rooms across 6 dark worlds, chase the top "Fang" medal time on each, spend your fangs on new hunters and upgrades, then drop into the Endless Vault when you want the descent to never stop.
I wanted a platformer that respects your time. The first chamber, Entry Shaft, teaches you the loop in about thirty seconds, and every room after it is a self-contained puzzle you can clear in a minute or two. Under that quick pace sits real depth: each level times your run and awards one of four medals, so a "win" and a "perfect" are very different things. Bronze just means you got out; Fang means you nailed the route.
The whole game runs in your browser on an HTML5 canvas, saves progress locally, and needs no account, install, or plugin. The soundtrack is generated on the fly — each world has its own low synth drone, so the Sunken Depths sound different to the Void Reaches before you even see them.
Ember Crypt, Ashen Keep, Sunken Depths, Burning Keep, Void Reaches and Ashen Rift — each with its own palette, hazards, two signature enemies, and a boss guarding the exit.
From nimble Vael to the tanky Razael and the fragile-but-fast Lirien, each hunter has different HP, speed and a signature move that changes your whole approach to a room.
When the story runs out, the Endless Vault keeps generating chambers downward. The Deep Vault layers in curse-and-blessing event cards for players who want the run to bite back.
Four medal tiers per level, 15 achievements, a fresh Daily Challenge worth 150 fangs, a daily Boss Rush, plus No-Hit and Speed Run challenges on every level you've cleared.
Every chamber follows the same three-beat rhythm, and once it clicks you'll read new rooms at a glance:
Each level also hides up to three treasures; grabbing all three in one run pops the Treasure Hunter badge, and a no-death clear earns the Untouchable achievement.
You start with Vael for free and unlock the rest with fangs. I balanced them around a simple trade-off — the tougher a hunter is, the slower or less mobile it tends to be — so your pick genuinely changes how a room plays.
The starter and still my go-to for time trials. Three HP, balanced speed, and the only hunter with a double jump — tap jump again in mid-air to reach ledges the others can't.
The tank: five HP but the slowest walk and no air jump. His Whip Strike (Shift/X) is a ranged attack that clears enemies without touching them.
Glass cannon: just two HP but the fastest ground speed, with a Shift/X dash that blasts past hazards on a short cooldown.
Four HP plus an Iron Shield that soaks the first hit you take each level. In the air his ability becomes a downward shield stomp.
Fast and fragile at two HP, but she phases through one wall per level with Shift/X — perfect for skipping a nasty stretch of hazards.
The endgame unlock. Three HP, fast, and every kill restores one HP — a passive lifesteal that rewards aggressive play in the Endless Vault.
41 handcrafted levels across six worlds — Ember Crypt (6), Ashen Keep (5), Sunken Depths (6), Burning Keep (9), Void Reaches (9) and Ashen Rift (6). The last three are gated behind fang unlocks. Some worlds add environmental systems: cold zones chill you, poison zones tick down your health.
The Endless Vault drops you into an unbroken descent — go as deep as you can and chase the depth-5, depth-10 and depth-20 achievements. The Deep Vault adds event cards between chambers: blessings like Frenzy (double fangs) and curses like Famine and Cursed Fog that ratchet the risk up the further you go.
Boss Rush strings the world bosses together for a daily limited-attempt gauntlet with a crown to claim. The Daily Challenge serves one seeded level each day for a flat 150🦷, and a login streak and rotating Daily Deal keep giving you reasons to come back.
Any cleared level can be replayed in No-Hit mode (finish without taking a hit) or Speed Run mode (beat the Fang time), each paying bonus fangs. Between the medal chase, treasures and challenge modes, a single level has a lot more to give than one clear.
Everything you earn funnels into the Reliquary. There's a 13-node upgrade tree across four branches — Combat (extra damage, max HP, a shield charge, a once-per-run auto-revive), Mobility (speed, jump height, air jumps), Economy (more fangs, double-drop luck, treasure sensing) and Survival (invincibility frames, coyote time, post-boss regen) — plus 15 achievements, a 30-tier progression pass, and cosmetic auras, trails and sigils.
Yes. The full game plays free in your browser with no download and no account. Some later worlds and cosmetics can be unlocked with fangs you earn in-game.
41 handcrafted levels across 6 themed worlds, each ending in its own boss fight, plus the endless modes that generate chambers indefinitely.
Yes — on touchscreens you get an on-screen joystick plus jump and ability buttons. The game adapts to portrait and landscape.
Your medals, fangs, hunters, upgrades and achievements are stored locally in your browser between sessions. Fangs (🦷) are the single currency — spend them in the Reliquary on new hunters, the 13-node upgrade tree, and cosmetic auras, trails and sigils.
