Delverium Early Access: what is playable after the demo?

The developer specified a simultaneous release at September 21, 1 p.m. PDT / 9 p.m. BST / September 22, 5 a.m. JST. The launch announcement now confirms Early Access is available. The two dates describe timezone differences, not separate content editions.

The October 25 Halloween update adds enemies, bosses and craftables. Several potion and crafting recipes change, and high-tier bows now require deadwood. Inspect current recipes before gathering. Expanded NPC behaviour and quests remain future work; the notes promise no completion date.

The October 31 patch v0.1.1.1949 puts the build version in the bottom right of the main menu, so you can now match your game to a guide's stated build. It also fixes the Demon Heart's range being too high, the inventory not refreshing after using energy weapon ammo, and a flesh impact sound, and it adds the latest translations. It adds no recipes or items. Kingy hasn't tested this build.

Sagestone’s launch-week reply says health recovery currently comes from food; potions provide other buffs. This is a design choice, not evidence of an undiscovered healing-potion unlock. The developer may change it later.

Kingy has not tested consumption controls, instant healing versus regeneration, stacking or behavior under attack. Record the food, build and visible result if recovery differs from its tooltip.

1. Inspect a food item’s health effects, then check its actual recipe requirements. Use the current-build tooltip instead of importing a preview recipe.
2. With health missing, use the food via your current controls. Compare health and active effects before consuming another item.

Sagestone says v0.1.0.2 fixes NPCs pending a respawn at a new location getting stuck after a world reload. The same patch note says old saves with NPCs already stuck still require manual room reassignment. The fix for future reloads is not an automatic repair of that existing state.

If your NPC was already stuck before updating, check the NPC's room assignment in that save and reassign the room manually. The patch note does not identify the exact menu sequence, whether the room must be changed twice, or whether every stuck NPC will recover. Do not delete the world or reset the character based on this notice; record your installed version and the NPC's state if reassignment does not help. Kingy has not tested this recovery in-game.

The September 22 developer reply described an intentional restriction. October 3 update v0.1.0.3 supersedes that blanket limit for flooring and torches: both are now flagged for underground placement. It does not establish that all buildings or NPC homes can be placed underground. Compare the selected item and current placement feedback before gathering for a larger structure. Kingy has not tested placement.

Sagestone announced Steam Deck verification before launch. That status does not supply a Kingy frame-rate measurement or a universal settings preset. Exact opening recipes, NPC room requirements and animal handling are still awaiting checked gameplay evidence.

1. Resolve your character-import choice before starting; a new world is required after the demo.
2. Choose solo or the appropriate co-op session, then inspect the controls shown by your installed build.
3. Pick one early task such as a shelter or crafting goal and read its actual recipe requirements before gathering.
4. Keep the world name, current task and missing materials in your progress notes.
