The full game launches at $4.49 with a 10% off introductory offer ending October 9, 2026 (base price $4.99) and ships with Steam achievements, family sharing, and the standard Steam library, wishlist, and curator sale features listed on its store page.

Steam AppIDs

The full game is published by Idea Garden Games under AppID 3972410, and the demo is published under AppID 4656850. Steam search returns exactly these two entries when you look up Black Cat Book Club, which matches the Steam store description listing no separate app ID for an earlier release.

Steam-only features

Both products use the standard Steam achievements system, Steam library entry, Steam Cloud where enabled by the developer, and Steam family sharing. The demo at AppID 4656850 currently lists six achievements; the full game's achievement count is not listed on the store page at research date.

Wishlist, follow, and curator sale

Players can wishlist or follow the full game through the Steam store page. The page lists standard Steam Cloud and family-sharing entries. Steam Deck verification is not announced as of 2026-09-29; the developer can request verification after launch, at which point Steam will surface the verified or playable badge on the store page.
