Allumeria Update History: Every 0.15 Patch, Summarised

0.15.4 — “Do Not Click Here” (31 August 2026)

Two lines, one of them significant: the “Click Here!” text was removed from the Compendium to comply with Steam Deck verification, replaced with an input icon. And the try/catch around Mesh.Draw became a null check — the tidier version of the 0.15.3 crash mitigation.

0.15.3 — “Invisible Farmland Fix” (31 August 2026)

The patch with the progression change everyone should know:

• Forest Keys no longer drop until you have defeated the Forest Spirit. Older guides describing a 20% key drop from forest enemies are now wrong.
• Fire no longer grants invincibility frames, and deals 6 damage every 30 ticks instead of 2 every 10.
• Minimum light level for comfortable sleeping dropped from 5 to 1.
• Iron and silver ingots got more contrast between them — a small change that stops a real inventory mistake.
• Dynamite had the wrong material assigned, making it indestructible; wet soil sometimes stopped chunk meshes generating; paint roller fixes.

0.15.2 — “This Room Ain’t Big Enough for the One of Me” (30 August 2026)

The NPC repair patch, plus early-game balance:

• Minimum light calculation changed; placed lava no longer interferes with a room’s minimum light level.
• Comfort now updates automatically when you talk to an NPC instead of needing “check comfort” on the sign.
• Glass stairs and slabs no longer block direct sunlight — the fix greenhouse builders needed, and the patch notes apologise for it by name.
• Enemies no longer spawn too close to other players in multiplayer (spawn radius was per-player).
• New Adventure Guide nodes explaining the danger of night and how biomes work.

0.15.1 — “Melon pls fix” (29 August 2026)

The first post-launch patch, written after the developer read the launch bug reports:

• Attempted fix for the block-breaking crash; fullscreen state fixes; autosave corruption fix.
• Freezing damage raised from 8 to 30 per two seconds; drowning from 1 HP to 10 HP per breath.
• Armoured Potion buffed from 4 defence to 12.
• Snow crates could be mined early, skipping progression — fixed.
• Forest keys and glass shards fixed in multiplayer; ladders given the correct wood material; palm planks made craftable; the hold-space item ID overlay removed.

0.15.0 — Early Access launch (28 August 2026)

The build that turned the demo into a paid game. The headline systems:

• NPCs and housing — the Comfort system, NPC Signs, and four NPCs (Builder, Farmer, Merchant, Blacksmith), each with their own room requirements and shop.
• Snow biome — cobalt, pine trees, hot springs, the Freezing effect, the Snow Dungeon and the four-piece snow boss, plus the ice pickaxe that mines palladium.
• Desert biome — palm trees, quicksand, palladium, the multi-floor desert dungeon with its keys, spawners and purple fire, and the Desert Worm.
• Health and damage rebalance — every enemy, weapon and armour piece retuned; player health now starts at 100 and caps at 200; natural regeneration; a health bar instead of hearts.
• Adventure Guide — a node tree in the Compendium that expands as you discover things.
• Better inventory and crafting — auto-detected stations, crafting from open chests, greyed-out recipes, station tabs.
• Building — column and vertical slab shapes, wallpaper base blocks, siding, bookshelves, three new paint palettes, six new paintings.
• Steam Input controller support, third person on F5, a 3D biome system in 8×8×8 chunks, and 12 new achievements.
• The Alpha Shop was removed entirely; NPC shops replaced it.

Before that

The release date was announced on 13 August 2026, two weeks ahead, along with the $12 price, the 20% launch discount and a new trailer. Allumeria’s first public version was released on 9 February 2025, and the demo continued through versions 0.12 to 0.14.9.
