Demo, full game and platforms: what is confirmed?

Which version of the game am I looking at?

The Steam full game is Eternal Palace Sakura, App 2991310. Its store links the separate 夢幻桜楼閣 Demo, App 4070720. The Japanese title is 夢幻桜楼閣; it identifies the same game’s official Japanese branding.

Denneko Yuugi develops the game, and Steam lists Denneko Yuugi and Shochiku as publishers. Use those identifiers when checking whether a guide, download or report concerns the full game or demo.

Is the full game released, and why do dates differ?

Yes. Steam’s English store lists 4 November 2026, and the official launch announcement says the full game is available. The release-date announcement specifies 5 November at 00:00 JST. The two calendar dates reflect that stated release timing.

The official publisher page lists Steam and Nintendo Switch. This page’s reward data and latest inspected 1.0.1 update are Steam sources; identical patch versions or achievement behavior on Switch are not established.

Does the full game have progression after a run?

The current Steam description explicitly says new abilities, weapons and upgrades carry into future runs. The official achievement list provides concrete reward-condition targets, such as Starting AP and named Art unlocks.

That answers the broad progression question without documenting an exact claim screen or when each listed reward is applied. Use the Reward condition finder to look up the conditions, then read Starting AP and Arts capacity or Mugen Depth rewards for the differences between labels.

Will my demo saves or unlocks transfer?

The inspected first-party sources do not establish a transfer guarantee. A separate linked demo AppID alone does not prove either compatibility or incompatibility. Do not rely on a demo achievement, save, or unlock appearing in the full game until the game or developer explicitly confirms that behavior.

If you need clarification, specify demo 4070720 or full game 2991310, your platform, and the exact progress concerned when using the official reporting route.

What does the current Steam listing support?

The full-game listing specifies Windows, single-player, full controller support, Steam achievements and Steam Cloud. It does not list native macOS or Linux support. Steam Cloud is not a demo-transfer or lost-save recovery guarantee.
