changedINTERFACESteam post image•
addedINTERFACEWorld map: biome info and chunk details split into two clearer panels, with an opaque scrim behind so labels are easier to read. • World map — new heatmaps Off / Depth / Speed in the top right. Blue→yellow→red gradient based on the metric. • Preferences: new "Screen shake" toggle to disable every screen shake in the game. • Preferences: new "Discovery animations" toggle — kills the white flash and slide-from-bottom of the new-resource popup (the card just fades in at its final position). • Event sound volume separated from SFX and music. • Skill tree tooltips reworked (gold titles, better spacing). • Pickaxe / machine tab tooltips: follow the language live and clamped to the viewport. • Stats window: icons added for smelted resources (ingots, lenses, pure veinstone, alloy, core) with aligned labels. • Smeltery: "Fuel" label now updates live when you buy Fuel Mastery. • STATS button visible from the start of the game.
addedPRESTIGE & MASTERYPrestige window: new summary panel on the right showing the level and total bonus of each of the 6 mastery nodes. • "Machine & furnace discount" renamed "Master Engineer". • "Abyssal Core" tooltip: now states that cores ignore smelt bonuses. • Depth points counter tooltip: shows the actual interval after the Depth Intuition bonus.
removedBALANCINGFurnace price multiplier: ×1.5 → ×1.4 per furnace of the same type. • Jackhammer: base damage 3 → 4. • Machine Damage upgrade: +2 → +1.5 per level. • Machine Synergy upgrade: +5% → +1% per adjacent machine per level. • Abyssal Cores: no longer affected by smeltery skill-tree bonuses (1 smelt = 1 core). • Abyssal Shards: spawn rate ×10 (≈ one Shard per 50m instead of 500m past 10,000m), bringing a prestige cycle down to ~5 km. • Worm / Annihilator / Excavator: switched from split-damage to additive weighted — total per-attack emission is now ×25 (Worm), ×30 (Annihilator), ~×8 (Excavator) instead of ×1. Big machines finally outpace stacked jackhammers in endgame. • Big machines now crack Abyssal Shards faster: Seismic Hammer ×1.2, Blast Furnace Drill ×1.3, Excavator ×1.5, Mechanical Worm ×2.0, Annihilator ×3.0. • Prestige starting pack: ×10 on every base resource granted (was ×4 in the previous patch). Same tiers, same scaling — the goal is to make each prestige feel rewarding from the first second and avoid having to grind clicks all over again to rebuild your machines. • Upgrade base costs cut: Machine Speed 15→10 bronze ingots, Machine Damage 10→6 steel ingots (multipliers unchanged). Lower entry barrier so the early levels of these upgrades feel more accessible.
fixedFIXESFurnace compact view: now persisted per furnace type. • Auto-clicker more responsive on rapid multi-block sweeps (clicks/sec cap still respected). • Language picker that reappeared at every launch: fixed. • Depth indicator: removed the per-mine yield % shown next to the biome name (redundant info). • Trade window tooltip: live refresh and clamped to the right edge. • "New resource unlocked" popup: cleaned of vestigial upgrades. • Admin depth-jump button: now credits Abyssal Shards and applies harvest bonuses. • Admin "+1M / +1B of each" button: routes through the standard pipeline. • Background mines speed (heatmap): no longer overshoots with absurd numbers. • Manual save: custom slot name is pre-filled on the next Save. • Save dates (Load screen): shown in your local timezone instead of UTC. • Skill tree: depth points counter now refreshes live when a point is earned with the panel open.
