The Junkyard - a third dig site: 50 layers under Rudy's junkyard, with brick, grey gravel, scrap and crushed cars

Scrap - scrap blocks pay a little every time you hit them, not only when they break

Crushed cars - only the pickaxe breaks them; rigs and Biscuit leave them to you

The Old Quarry - a fourth dig site: 60 layers of limestone, dark basalt, silver and coal under an old stone quarry

TNT crates - break one and it blasts every block around it, and sets off other crates nearby; rigs keep away from them

Story - Uncle Rudy has new radio lines for both sites, and each one has something at the bottom

Old Bones' map - the last two pieces of the first map

Junkyard row - 10 new skills, open once you clear the Orchard: Shockwave IV, Car Crusher, Power Drill, Heavy Bits, Turbo Fans, Scrap Magnet, Scrap Dealer, Salvage, Safe Cracker and Fetch

Old Quarry row - 10 new skills, open once you clear the Junkyard: Blasting Caps, Rock Splitter, Hammer Drill, Tungsten Bits, Steam Engine, Demolition Crew, Silver Lining, Blast Pay, Strongbox and Dig Dog

More levels - Crit Chance, Crit Damage, Splash Damage, Hand Drill and Rig Cooling have 30-34 more levels each

The Orchard - a second dig site: 55 layers under an apple orchard, with its own grass, soil, mossy rock, gold and rare crystals

Roots - root blocks run down through several layers; break the top of a root and the one below it has half its health

Old Bones' map - Biscuit's treasure holds a torn corner of an old map, and each new site's treasure holds another piece

Site map - the map lies on Rudy's table; click it to pick where to dig next, see each site's layers and best time, and dig a cleared site again

Story - Uncle Rudy has new radio lines for the Orchard, and there is something at the bottom

Rudy's lot - the first dig site is rebuilt: Rudy's house, the street, cars and trees around a cleared lot

Light - warm evening light baked in Blender, with shadows on the ground, on the pit walls and on the blocks

Shadows - blocks shade the blocks around them, and rigs and Biscuit cast soft shadows

Pit walls - the walls of the pit show the rock layers of the site you are digging

Climb up - a button in the sidebar takes the camera up for a wide view of the town while the rigs keep digging

Layer meter - the meter shows the site's rock layers as blocks, with the layer you are on

Stats page - the game menu has a Stats page: play time, digs, blocks, clicks, money, crits, chests and each site's best time

Apple of My Eye - clear the Orchard

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
