Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“Jingjie: Probability Cloud - Nagumo's Dilemma is a systems-heavy carrier command game about uncertain scouting, report confidence, flight-deck timing, recovery pressure, and strike commitment. Early Access lets players help us test whether that command loop stays readable and rewarding across repeated battles.

We are also using Early Access to tune a fairness-bounded adaptive opponent. It responds to observable evidence and repeated habits without reading hidden player intent. Feedback is essential to make that counterplay understandable and earned rather than opaque or unfair. Players should judge the game by the playable build available now, not by future promises.”

Approximately how long will this game be in Early Access?

“We currently expect Early Access to last roughly 9 to 12 months. The schedule may change if feedback shows that onboarding, scenario structure, command readability, or technical stability needs more work than expected. We will update this answer when the schedule changes meaningfully.”

How is the full version planned to differ from the Early Access version?

“The planned 1.0 version is intended to add more scenarios, clearer long-form progression, stronger after-action tools, broader carrier-operation situations, refined enemy counterplay, and further work on settings, localization, performance, accessibility, and onboarding.

We also plan to deepen the adaptive opponent while keeping its evidence, limits, and reasons visible. These plans may change with development; the priority is that players can explain why a strike succeeded, missed, or arrived too late.”

What is the current state of the Early Access version?

“The current Windows build includes multiple authored scenarios, free play, and an endless sandbox. Its playable command loop covers blue-water search, contact confidence, report age and error area, the current left-side command surface, launch readiness, air-group scheduling, flight-deck pressure, CAP, recovery, strike commitment, and after-action analysis.

Manual, semi-automatic, and bounded automatic workflow modes are present with visible permissions, safety constraints, and manual intervention. The opponent can adapt to observable exposure and repeated habits without reading hidden UI or intent. The game is playable but does not yet represent a finished campaign; wider content, long-form progression, balance, onboarding, save/checkpoint behavior, performance, accessibility, and localization still need Early Access work.”

Will the game be priced differently during and after Early Access?

“The Early Access price reflects the content and polish of the current build. We currently expect the price to increase toward 1.0 as substantial content and polish are added. We will communicate any price change before it happens. Regional pricing may differ by territory through Steam.”

How are you planning on involving the Community in your development process?

“We use Steam discussions, bug reports, update notes, focused surveys, and play-session feedback. The most useful reports describe where the first-run flow, contact terminology, current left-side command surface, contact-to-strike path, workflow permissions, scenario pacing, performance, accessibility, after-action explanation, or adaptive opponent becomes unclear or unfair.

Development is not a simple feature vote, but evidence from players helps us decide what needs explanation, tuning, or redesign before 1.0. Any use of external playtest data beyond local game telemetry and internal simulation would be communicated separately and clearly.”

About This Game

Jingjie: Probability Cloud - Nagumo's Dilemma is a Pacific carrier command simulation set against the carrier battles of World War II. "Nagumo" refers to Chuichi Nagumo, commander of the First Air Fleet during the opening Pacific War operations and the Battle of Midway. The game is not a biography or a celebration of any wartime regime; it uses this historical command problem as a frame for uncertainty, delayed reports, flight-deck pressure, and decisions made before the truth is fully known.

You do not pilot aircraft or command from a fully revealed map. You read contact evidence, judge confidence, age, and error area, manage carrier operations, and decide when an uncertain position is good enough to risk a strike.

The current Early Access build includes multiple authored scenarios, free play, and an endless sandbox. Its command surface routes contact evidence through launch readiness, air-group scheduling, and a professional combat workflow, while manual, semi-automatic, and bounded automatic control remain visible and interruptible.

Every report has age, error, and consequence. Scouts can find a possible carrier, lose the trail, return low on fuel, or deliver information that is already going stale. The opponent adapts to observable evidence and repeated habits without reading hidden player intent.

- Imperfect intelligence instead of an omniscient map.

- Carrier operations shaped by time, flight-deck capacity, CAP, scouting, recovery, and attack opportunities.

- A contact-to-strike path with visible confidence, readiness, scheduling, and workflow consequences.

- Manual, semi-automatic, and bounded automatic workflow control with visible safety constraints and manual intervention.

- Multiple authored scenarios, free play, endless sandbox, and after-action analysis for replayable command problems.
