About this game

■ It looks like a terminal. That's the point.

Black screen. Neon green text. System logs scrolling forever. CPU load and memory
pressure climbing. To anyone glancing over your shoulder on the train, you are
debugging a complex production system.

What you are actually doing is connecting three or more matching symbols.

■ How it plays

You are an incident response engineer covering 16 data centers around the world.

- Pick a degraded node on the world map
- Travel there (the farther it is, the longer it takes)
- Patch the bugs on site (that's the puzzle)
- Earn experience and credits, then move to the next incident

Tokyo, Seoul, Singapore, Frankfurt, Sao Paulo, Cape Town and more. Travel time is
derived from real geographic distance, so crossing the planet actually costs you time.

■ Three numbers are trying to kill you

While you work, three resources keep rising:

- CPU — above 72% sectors of the board freeze and become unusable
- MEM — at 65% the minimum chain grows from 3 to 4, at 88% to 5
- TRACE — accelerates the higher CPU and MEM get. This is your real timer

If any of them hits 100%, the session is lost. Clearing three at a time will never
outrun the load. You have to build long chains and cash them in before the multiplier
expires.

■ Fatigue, and the engineer ladder

Deploying and traveling makes you tired. Fatigue only recovers in real time, and
going in exhausted means starting from a worse baseline. Knowing when to rest is
part of the game.

Patching bugs earns experience and promotions: INTERN, ENGINEER, SENIOR, STAFF,
PRINCIPAL, DISTINGUISHED, FELLOW — and beyond. The final rank is SINGULARITY at
level 85.

Restore all 16 nodes and the world is reinfected at a higher severity. It does not end.

■ Made for

- Short sessions with real pressure
- Not wanting to look like you are playing a game in public
- People who like black terminals

■ Ads and purchases

Free to play all the way through. Ads are mostly opt-in — watch one to skip travel
time or recover fatigue, only when you choose to. A one-time PRO license removes ads
permanently.
A hacker-skin match puzzle. Fly the globe, patch the nodes, climb the ladder.
