Skill tree
  • Skill tree - 42 skills in four branches: Pickaxe, Rigs, Fortune and Biscuit

  • Rows by depth - new rows open at layers 12, 25 and 40; the Next dig row and Biscuit's branch open from your second dig

  • Frenzy - fast clicking fills a meter; when it is full, every swing crits for a few seconds

  • Treasure chests - chest blocks on some layers pay part of the layer's value, some of them golden

  • Fortune - Layer Bonus, Interest, Lucky Strike, Jackpot and Bargain

  • Dig Buddy - Biscuit digs with you, sniffs out chests and turns up bones

Rigs
  • New rig - a drill pod on four legs with a spinning bit

  • Skills you can see - rig skills change the bit's shape and recolour the rig

  • Seventh rig - a skill adds one more rig to the six you can build

Pickaxe
  • Crit Chance, Crit Damage and Splash Damage - new pickaxe upgrades

  • Shockwave - a skill that spreads your hit to the blocks around it

Ending
  • Treasure pit - Biscuit waits in a pit in the bedrock under the last layer, and the scene is longer

  • Results card - your time, blocks, money, chests, biggest crit and skills, compared with your best dig

  • Golden chest - later digs end with a golden chest and a dig bonus

Menu
  • Game menu - Esc opens a sidebar with your progress, best time, music and sound volume, credits and New game

  • Welcome back - the same menu greets you when you continue a save

Achievements
  • Researcher - learn every skill in the skill tree

Achievements
  • Tinkerer - now unlocks when you learn 10 skills

Mining
  • Pixel cracks - blocks crack in pixel-art stages from the middle of the top edge

  • Layers - rock comes in bands with iron veins; gems and rare crystals appear from your second dig

  • Aiming - aiming at empty space no longer mines the blocks next to it

  • Outline - a thinner outline on the block under the cursor

Balance
  • First dig - a gentler start and many small upgrade levels; the first dig takes about an hour to an hour and a half

  • Rigs - stronger rigs that do about half of the digging by the middle of the dig

  • Late game - the last upgrade levels cost more, for a final push to the bottom

UI
  • Sidebar - Pickaxe, Rigs and Skills tabs in one sidebar on the left; the camera keeps the chunk centred

  • Tooltips - every upgrade explains what it does

  • Volume sliders - new sliders you can click or drag

Removed

3 changes
Rigs
  • Rig Engines - rigs already find their way well, so the upgrade is gone

Workshop
  • Workshop - crafting and materials are gone; ores pay money instead

  • Save carries over - materials become money, crafted parts become skills, extra rigs and Rig Engines levels are refunded
