How to Play Strata

Strata is a mining descent arcade game in which you pilot a drilling pod through a destructible tile world. You begin above ground at a surface depot. From there, gravity pulls you down — use upward thrust (hold the up arrow, W, or Space) to control your descent. When you land adjacent to a rock tile, hold a direction key to drill through it. Deeper strata hold richer ore: coal near the surface gives way to copper, silver, gold, ruby, diamond, and the rare relic below row 180. Fill your cargo hold, then fly back up to the depot to sell everything automatically. Credits bank permanently — you never lose what you have already sold.

Each trip ends in one of three ways: you return to the surface and sell, you run out of fuel underground (a strand event — cargo is lost but banked credits survive), or hull heat destroys your pod below row 110. Between trips, spend credits at the Pod Upgrades panel on a three-branch tech tree: Drill for speed and rock hardness access, Logistics for fuel and cargo capacity, and Salvage for better sell prices and a safety net on dangerous runs.

Strata rewards planning over reflexes. The drill is slow, fuel is finite, and the deeper you push the harder it is to climb back out. The tension between "go deeper for richer ore" and "return before fuel runs out" drives every run.

Controls

• Left / Right (Arrow Keys or A/D): Drive along the ground (open space) or steer in flight — burns half fuel on the ground, full fuel in the air
• Up / W / Space (hold): Upward thrust — burns fuel
• Down / S (hold while grounded): Drill downward into the tile below
• Left / Right (hold while grounded next to a solid tile): Drill sideways through rock
• U (at depot): Open the Pod Upgrades panel
• ? or /: Toggle the help overlay with ore values and controls
• Mobile: Three on-screen buttons — left, right, and thrust — with drill triggered by holding the direction toward a tile

Tips and Strategy

• Pre-carve a return shaft: On your way down, drill a vertical shaft through the center columns. The return trip is almost free if you can fly straight up through empty space rather than re-drilling your path.
• Watch the cargo indicator: When the DEPOT ▲ arrow appears in the HUD, your hold is full. Every ore you drill after that drops as a timed pickup — collect it by landing on it, or it expires in 10 seconds. Return to the depot instead of drilling more.
• Prioritise the Tungsten Bit early: At 40 credits (about one coal trip), level 1 speeds up drilling noticeably. Level 2 unlocks medium-rock rows 41–90, which is where copper and silver live. Without it, you are stuck in topsoil.
• Fuel tank before depth: The Auxiliary Tank upgrade (50 credits) pays for itself on the first run it enables. Without extra tank capacity, reaching gold ore and returning safely requires nearly perfect fuel management.
• Buy Haul Insurance before pushing deep: A strand event at row 140 with a full diamond cargo can lose 500+ credits in one stroke. Insurance level 1 (120 credits, Salvage branch) guarantees you keep half. Level 2 keeps three-quarters. The break-even is a single prevented loss.
• Surface Winch is the run-changer: At 380 credits (Logistics, after tank level 1), the Surface Winch teleports you to the depot once per trip with cargo intact. Use it after filling your hold at depth 100+ and you turn a 40-second climb into an instant sell. This is the largest single return-on-investment upgrade in the tree.

What Makes Strata Different

Most mining games use a grid-cursor or turn-based drill loop. Strata uses real-time physics: the pod falls, bounces off tile surfaces, and can be steered in the air. This makes routing feel like a flying puzzle rather than a click-to-dig board game. You plan where you want to end up, then fly there — and you have to actually reach the ground before you can drill, which means fuel planning starts the moment you leave the depot.

The ore value ladder is steeper than in comparable games. Coal at 4 credits is genuinely bad compared to diamond at 120. This means a player who invests in Drill upgrades to reach deep strata earns credits an order of magnitude faster than one who stays shallow. The tech tree branches work because they each unlock a different kind of depth advantage: Drill gets you there, Logistics lets you stay there longer, and Salvage makes each trip more efficient. All three paths are always available — the inflation mechanic means buying many levels across all branches is more expensive than focusing on one, creating natural specialisation without locking anyone out.

The Ore Value Ladder

Understanding the ore value table is the fastest way to improve at Strata. Coal (rows 4–30, 4 credits) and copper (rows 18–55, 8 credits) are the apprentice tier — useful for buying your first upgrade but not for sustained income. Silver (rows 45–85, 15 credits) and gold (rows 75–125, 30 credits) are the mid-game backbone: reachable with basic drill upgrades, and densely enough packed to fill a cargo hold in a single pass. Ruby (rows 110–170, 60 credits) starts in the heat zone, meaning you need at least Rockbreaker to reach it and Coolant Loop to stay there comfortably. Diamond (rows 150–240, 120 credits) sits in the magma zone where heat rises at 16 units per second — survivable with Coolant level 2 but genuinely dangerous without it. Relics (row 180+, 250 credits each) are rare spawns with a custom glyph tile; even one in a cargo hold transforms an average run into a great one.

A Brief History of Mining Descent Games

The mining-descent genre traces back to Motherload (2004), a Flash game that established the core loop: descend, drill, return, upgrade. Dome Keeper (2022) refreshed the formula with a tower-defense surface element. Strata strips away the surface threat and focuses entirely on the descent risk — fuel, heat, and cargo weight — while adding real-time physics that earlier tile-drill games lacked. The result is closer in feel to a skill platformer than a resource manager, even though the economy layer is the game's long-term hook. Players who come from Motherload will recognise the ore ladder and the upgrade tree; players who come from physics platformers will recognise the flight model.
