0.3.5

5 August 2026

Aetherium tier — a whole new band of content past Rebirth 15.
Serpentine Refinery — a big S-shaped machine, the strongest ingot boost in the game (x40). Material snakes in at the foot and out at the far tip. Rebirth 18.
Aetherium Dropper — an 11-tile lopsided crystal mass, one cell bigger than the Singularity and far richer. Emits from the crown tip. Rebirth 18.
Aurum Press — a cross-shaped machine, and the first refinery that boosts a CRAFTED good instead of an ingot (x6). Rebirth 20.
Regalia Bench — a crown-shaped combiner, the widest piece in the game. Scepter + Gemstone becomes Regalia, the new apex good. Rebirth 20.
Prism Loom — a stair-shaped combiner joining your two late chains. Gemstone + Power Core becomes a Prism Core. Rebirth 20.
Processors tab — the Processor now lives in its own dropdown alongside three new variants.
Chain Processor — takes a feed on BOTH ends, so two belt lines can sell into one square. Rebirth 5, then 300 boxes. Max 3.
Golden Tipped Processor — gilded rollers pay x1.5 on every sale. Rebirth 8, then 200 Power Cores. Max 3.
Diamond Tipped Processor — x2 on every sale, the best there is. Rebirth 15. Max 3.
Cross — a 4-way crossing so two belt lines can pass through each other without merging. It has been in the game's files for a long time but was never buildable.
Clear Board button — sells every piece at once, with a confirmation showing exactly what you get back.
Drag to erase — hold and drag with the eraser to sell a whole run of belt in one stroke.
Rebirth is now an event: a screen thump, layered sound and a card showing the run you just banked.
Finished buildings flash green and pop as the engineer steps away.
Selling a building now takes it apart piece by piece and pays out with a green $.
The engineer powers up and down with a voice, breathes while it waits, and celebrates a level-up with a ring and a Lv badge.

Rebalanced the tech tree: every percentage upgrade is 10% weaker per level. Because those upgrades multiply together, that works out to roughly a 2.4x cut to late-game income. Tech still resets on rebirth as it always has, and Prestige upgrades are untouched.
Unlock popups now cover the whole game. 22 pieces from the Silver Dropper onward used to unlock in complete silence, including every aura tower, the Bridge, and all the late-game benches.
The Rebirth button now tells you WHY it is locked, and says when a whole new tech tier has just opened under you instead of silently going grey.
The Parts Guide is spread over five pages so nothing is cut off, with proper room between each heading and its first entry.
Turning the quick bar on or off no longer shifts the whole board sideways.

Progress bars no longer snap to empty when you buy a process-speed upgrade mid-craft.
Contract and achievement Tech Point rewards were massively inflated for late-game players — a single contract could pay out billions. Rewards now track what you can actually spend.
The Compact button under-reported its own payout by up to 13x. It now shows the Tech Points you will actually bank.
The Silver Dropper — your first ore upgrade — unlocked with no announcement at all.
The Ring Setter and Necklace Bench displayed as "RingSetter" and "NecklaceBench".
Six pieces were missing their colour on the board: Enricher, Gem Cutter, Alloyer, and all three aura towers, which looked identical to each other.
The Bridge was missing its colour stripe in the Conveyors menu.
The hover info card laid its text out sideways instead of stacked.
Engineer level-ups were tracked internally but never shown or heard.

The standalone Processor button — it now lives inside the Processors tab with the three variants.

Processors on the Network screen keep a gold flash stuck on them after a sale.
The Prestige shop does not scroll, so the lowest upgrades can be hard to reach.
The board sits slightly left of centre.
