Update - New content and a long list of fixes

Content updates

• Three lost relics are hidden in every mine — A reason to dig sideways instead of straight down.
• The Museum now stands on the surface: a stone building with three lit display cases. Carry a relic home and it goes up on a plinth, lit, and stays there for the rest of the run — through saves, reloads and late joins. (We will polish and add more to the relic system in the future)
• Lamps burn fuel now. A full one lasts about twenty minutes and visibly dims as it goes, down to a faint glow — it never goes fully dark. This does walk back what the Builder Update said about lamps never needing refuelling; a lit base is something you keep lit now.
• The Fuel Jug ($120) — a carryable can. Fill it at the surface, haul it down, and top up five lamps per jug. Any player can pick up any jug, so a crew can stash full ones around the mine for whoever is nearest. Every jug remembers where it was left and how full it was.
• Gas leaks. Break a pocket open and it seeps out into your tunnels — one tile every three minutes, up to three tiles, and only along a path it can actually reach. You no longer have to mine gas to set it off: walk into a cloud with an open flame and it goes up, chaining back into the pocket that fed it. The electric headlamp still clears it safely.
• Lamps mount on the walls inside an elevator shaft, so a deep shaft can be lit all the way down.
• Elevators stack. Put a second kit under an existing one to keep going deeper, and ride the whole run in one go.
• 25 new achievements covering the build system, lamps and elevators, cushion bouncing, gas, radiation and the relics.

Bug fixes

• Dynamite can no longer blow through bedrock, which used to drop you out of the world. Charges refuse to attach to bedrock at all now, so you can't waste one.
• A platform mounted on a block's lower edge bridges a gap in a tunnel floor — you walk across it instead of dropping through or not being able to step up onto it.
• A platform can be placed on a cell that already holds a ladder, so you can build a landing part-way up a run. It only worked the other way round.
• Lamps can be anchored to player-built platforms — on top of one, or hanging underneath one mounted on a lower edge.
• Climbing a ladder into a platform steps you up onto it instead of bouncing you against it.
• Down + jump drops you through a platform reliably, even with a ladder on it. You no longer have to stand in exactly the right spot.
• Falling past a ladder without touching it no longer cancels the fall, so the cushion at the bottom gives you the bounce you were owed.
• Cushioned landings have a sound and a thump. They used to be the one impact in the game that was completely silent.
• An elevator whose shaft stopped short could never be removed or destroyed by anything, and it kept its column locked forever.
• Elevators can be pulled out in Remove Mode, refunding a kit.
• An elevator keeps extending downward when you break the rock beneath it. You no longer have to pull it out and set it down again.
• An elevator freed from a boulder digs on to its full bought depth — a 10-floor kit finishes all ten floors.
• Elevators stop at the depth their kit was bought for; mining underneath one no longer drags it deeper than it should go.
• Ore an elevator digs through now drops on the ground for anyone to pick up instead of being destroyed. A shaft through a copper vein was pure loss.
• The surface buildings stand in the same place for every player in a lobby.
• "New Depth" milestones no longer replay from zero every time you load a saved world — your record carries over. (The UI may still be saying new depth though, will fix next)
• The shop sits on the ground instead of floating a few pixels above it.
• On a controller, the pause menu and the host public/private screen no longer drive your character around while you navigate them.
• The world-creation screen no longer runs off the bottom of the window with Advanced settings open.

Polish and quality of life

• When a block is too hard, the game names which rock it is and which tool opens it — "Hard Rock needs a Hand Drill I — your Pickaxe III cannot break it" — instead of just telling you to upgrade.
• The shop warns you when the next tool is faster only and still stops at the same rock, so a speed upgrade can't be mistaken for a way through.
• Picking up the Core says "The Core has locked onto you" — while you carry it, every bit of the radiation is aimed at you and nobody else takes any.
• An arrow beside the radiation readout shows whether your dose is rising or falling, so you can tell that backing off is working.
• Anyone being irradiated glows green, and whoever carries the Core pulses. You can see at a glance who is taking the hit and who is safe.
• Radiation now fades wherever you are once you're clear of the Core, instead of only at the surface. The surface is still four times faster.
• Cushions bounce. From 5 tiles up — about half a tile at 5, growing with the drop, up to 10 tiles from a real plunge, and a big bounce lands and bounces again until it settles. A ladder only catches you if you actually grab it, so falling past one at speed is no longer a free landing.
• A prompt tells you which button picks up the Core, a relic or a jug — and which one puts a relic into the Museum.
• Lamps show a fuel gauge once they start running low, red when they're nearly out, and nothing at all while they're healthy.
• Pick up a jug and every lamp shows its gauge, so you can see exactly how much is in each one and which you can skip on your round.
• Carrying a jug puts its remaining fills in the stat panel, next to Depth.
• Set gas off and the game tells you the electric headlamp would have prevented it. Clear gas with that headlamp and it gives you the credit.
• The build menu is seven keys instead of twelve — press a key again to cycle the variants inside it (lamp tiers, elevator sizes, platform/cushion). The Q and E shortcuts are gone; the build menu is the only way to place now.
• Remove Mode stays active after you remove something. To move a thing: remove it (you get it back) and press its key again.
• The bumpers cycle Remove Mode as part of the item ring, so you can step into it and back out without letting go — and the left trigger no longer flickers in and out of it as you squeeze.
• The screen is framed blue while building and red while removing, with nothing while mining, so the active mode is obvious at a glance.
• Mode reads in the stat panel under Depth and Backpack — "Mode: Mine / Build / Remove" — instead of a wide banner of control hints across the bottom.
• Real spacing along the bottom of the screen: the controls strip, health and light bars, item bar and hints were touching each other.
• Menus scroll and resize to your screen instead of assuming one.
• Every line of text in the game is translated into all ten languages, and changing language mid-game updates the whole HUD, shop and pause menu instead of leaving most of it in the old language until you restart.

Old saves load fine. Everyone in a crew needs the update to play together.

Keep the reports coming — that's where this list came from.
