Direct movement, auto-firing weapons, and a horde that never stops. Built around a deep 14-element reaction system where the combos emerge by design, not by a designer placing them.
Move with WASD or arrows. Weapons fire themselves. Collect gems, level up, survive. (Loads a WebAssembly build — give it a moment.)
The two halves of the genre, done together: the immediate, one-thumb control of Vampire Survivors with the transformative build-craft of Nova Drift.
360° movement on a single stick; every weapon auto-fires and auto-targets. Playable with one thumb on a phone, no aiming required.
Upgrades don't just add numbers. Mods change how weapons behave, and evolutions transform them entirely. Two runs play completely differently.
A deterministic, data-oriented core renders thousands of enemies and projectiles at a stable frame rate. Built for the densities a long run reaches.
Every weapon and effect speaks a shared language. Apply one element to build an aura and stacks; apply a second and trigger a reaction. The combinations are where the game lives.
Cold aura + Lightning = Superconduct. Fire + Poison = Combustion. Cold + Sound = Shatter. Void + Aether = Paradox.
A 14×14 matrix of reactions, all tunable in the open Balance Bible.
Every weapon, enemy, mod, and elemental reaction in this game is designed and tuned in a live web tool — with computed DPS, time-to-kill, and the full reaction matrix. It's public. Poke at the numbers.
Open the Balance Bible →Built deterministic from day one so co-op multiplayer can be layered on without a rewrite.
