## What is Stellalyzer?

Take the watch. The signal is real. The answer is not obvious.

Stellalyzer is an offline-first space-operations strategy game about making defensible decisions under uncertainty. Read the evidence, build a plan, commit limited resources, and face the consequences in a mission-control world shaped by three researchers with different strengths.

FIVE OPERATION MODES
- Impact Ops: weigh trajectories, timing, and mitigation tradeoffs.
- Signal Ops: separate meaningful structure from noise.
- Conjunction Ops: protect orbital margins under pressure.
- Cosmic Explorer: manage deep-space observation and communication.
- Sample Return Ops: balance scientific value against mission risk.

A CAMPAIGN THAT REMEMBERS
- Navigate a 10-chapter campaign with branching outcomes.
- Carry research gains, investments, and even failed decisions forward.
- Build six investment paths and recover from soft deadlocks through deliberate replanning.
- Continue beyond the Good End into a high-difficulty post-game story arc.

LEARN BY PLAYING
- Tackle 75 curated anomaly cases grounded in astronomy and space-science concepts.
- Compare counterfactual plans and understand why outcomes changed.
- Build a local research archive, mastery profile, and researcher-specific record.
- Review explainable debriefs with uncertainty ranges, top factors, and after-action analysis.

BUILT FOR REPLAY
- Chase multiple best records, researcher titles, endings, and branch variations.
- Revisit short challenges or attempt full campaign runs.
- Use deterministic simulations so the same choices remain reproducible.

PRIVATE AND OFFLINE-FIRST
- No account and no advertising.
- Progress and learning records stay on your device.
- After a verified purchase, unlocked content remains available offline.
- Backup, export, support, and sharing occur only when you choose them.

Stellalyzer is a fictional learning game. It is not real mission-planning software or operational guidance.
