Slots, equipment, wallet, world loot, quests — AAA-grade RPG inventory with atomic trade semantics, 579+ tests, and a SaveStack-native persistence layer. The inventory system to reach for when shipping an RPG, not prototyping one.

InventoryFlow is built directly on SaveStack — atomic file writes, AES-GCM encryption, HMAC integrity, schema migration with rollback. Three lines of code persist an entire world state.

LoreFlow is the Editor-side AI content pipeline for Unity — design a Lore Bible as a ScriptableObject tree, then generate typed ItemDefinition assets via guided wizards. BYOK (bring your own Anthropic or OpenAI key); zero runtime cost; nothing leaves the Editor at runtime, so no player-side DSGVO surface.
InventoryFlow ships with the receiving end already wired — ItemRegistry and ItemDefinition are ready for batch import from the LoreFlow approval queue. Buy InventoryFlow now, plug LoreFlow in when it lands.

Yes. InventoryFlow is built on SaveStack’s saver framework — the integration isn’t an afterthought, it’s the architectural foundation for atomic writes, AES encryption, and schema migration. The bundle exists exactly to make this pairing painless.
The domain layer is pure C# — ItemDefinition, Inventory, EquipmentSet, Wallet have no MonoBehaviour dependencies. Drop the InventoryHost bridge MB onto an existing character GameObject and the inventory works. Equipment slots bind via tag-mask, so weapon types from an existing setup map cleanly.
Yes — full source under the Asset Store EULA. All 11 asmdefs ship as readable, editable C#. No DLLs, no obfuscation.
IL2CPP-AOT-safe by design — no reflection.emit, no dynamic code paths. Tested on Windows, macOS, Linux standalone, WebGL, Android, and iOS-IL2CPP. The pure-C# domain layer means no Unity-specific surprises on player platforms.
For the first 6 weeks after Asset Store approval, InventoryFlow is €34.99 instead of €49.99 (30% off). After the launch window, it returns to standard pricing. Sale and bundle eligibility are managed through the Asset Store publisher backend.
Reviewer access, screenshots, fact sheet, hands-on guide, and a no-strings code for evaluation builds — everything press, YouTubers, and indie-dev podcasts need to cover InventoryFlow.
