Fluxgates

Every run is a factory you've never built before.

Draft nodes. Wire them together. Resources flow. Rooms demand throughput.

Drag, wire, press ▶ Run Production.

What you do

Each room sets one objective: collect 400 energy, hold ≥20 matter/tick for 20 ticks in a row, clear every track before the run ends,... and hands you a credit budget.

Nothing is on a timer while you build. Wire sources into amplifiers into sinks, buy the piece you're missing from the room shop, take as long as you want. When the pipeline looks right, press ▶ Run Production.

The simulation runs a fixed number of ticks and scores what flows into your sinks. Fall short and you can rewire and retry, each retry costs budget. Clear it and you choose: bank the reward, or push for the bonus target and risk carrying a penalty into the next room.

Between rooms you draft new nodes and relics from the Spoils screen, then pick your path through a branching map of rooms, shops, rests and events. Your pipeline grows, warps, and either carries you to the boss or seizes up on the way.

What makes it different

• A combo engine, built fresh every run. Individual nodes are simple. The run is about the multiplier chain you stumble into: an amp that scales with the amps upstream, a capacitor that stores three dead ticks into one spike that clears the threshold... Factory-game parts, deckbuilder pacing.

• Packs decide what run you're playing. Eight packs, each a complete strategic twist on the same substrate: Chaos gambles, Toll pays a known price, Power stacks raw multipliers, Routing shapes the flow, Tempo reshapes when it arrives, Synthesis converts anything into anything, Economy turns credits into throughput. Toggle them at run setup to concentrate the draw.

• Difficulty you opt into. The Heat Pact lets you accept conditions: tighter objectives, leaner budgets, volatile nodes, costlier retries,... for more Heat, and more Flux when you win. Clear a Heat tier to unlock the next.

A factory that stays.

Runs end. The Foundry doesn't. Every run, won or lost, banks its last room as a blueprint; wire them together on a floor that stays, and what it lights is what your next run starts with. Nothing runs while you're away.

Features

• 71 nodes across 8 packs: sources, amplifiers, splitters, gates, converters, sinks,...

• 23 relics - permanent, run-long rule-benders

• 51 rooms and 5 bosses - some of them unlocked by how you win, not by how often

• A branching map each run with rooms, elites, rests, events,...

• A 42-node research tree you feed, not buy. It runs on what your Foundry makes

• The Foundry - every run, won or lost, leaves its last room behind as a blueprint. Place blueprints on a factory floor that stays between runs and wire what they make into the research trees and pack gates: what lights is what your next run starts with. Nothing runs while you're away

• Pack Filters - an unlock that lets you switch packs off at run setup and concentrate the draw into the build you want

• A loss still pays Flux - no run is wasted

• Full English and French - text and UI

Demo

A free demo is available. It covers the opening rooms and the first boss, and your progress carries nothing into the full game but the knowledge of how to wire a merger. The Foundry is in the full game, not the demo.

Made by one person

Fluxgates is built solo. Wishlist it to get told the day it launches - that signal is the whole marketing budget.

The Discord is where builds get argued about, and the in-game 🐞 button files a bug straight onto the tracker.
