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
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
Crit Chance, Crit Damage and Splash Damage - new pickaxe upgrades
Shockwave - a skill that spreads your hit to the blocks around it
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
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
Researcher - learn every skill in the skill tree
Tinkerer - now unlocks when you learn 10 skills
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
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
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
Rig Engines - rigs already find their way well, so the upgrade is gone
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
