Mining Run

Mining Run

Dig. Haul. Upgrade. Descend. Repeat. You get one timed dive at a wall of rock. Click to break it, watch the ore pop out - coal and copper if you're unlucky, rubies and diamonds if the vein is kind - and haul everything to the surface before the time runs out. Cash your haul into gold, spend it on upgrades that sharpen your pickaxe, stretch your lungs, and bend the loot table in your favor, then drop one layer deeper where the rock is tougher and the veins are richer. Your gold, upgrades, and depth are saved between sessions, so every session picks up exactly where you left off. It's small. It's fast. It's a complete loop - a menu, a run, an upgrade screen, meta-progression, and a save file - the kind of thing that usually takes weeks of gluing systems together. This one took none of that. Here's the point of the whole game:

Every system here is a drop-in component

Mining Run has no custom engine underneath it. There is no bespoke inventory code, no hand-rolled save format, no upgrade framework written for this game. Every mechanic you touch is a portable component copied straight into the project and wired together:

What you see in-game	The component doing the work
The ore you haul out of a run	Inventory System
What a rock drops when it breaks	Loot Table System (weighted by rarity)
Gold you spend between runs	Currency System
Sharper Pickaxe · Deeper Lungs · Vein Sense · Lucky Strikes	Upgrade Tree System
The "+Iron" pops on every dig	Floating Text System
Screen shake on a hit, a flash on a rare find	Screen Effects System
"Diamond found!" toasts	Notification System
Gold, upgrades & depth surviving a restart	Save System

Swap any one of them out and the rest keeps working. The upgrade tree never touches your wallet directly — it asks a payment callable to spend the gold. The loot table just produces item stacks and the game decides where they go. That's the whole design: logic split from UI, systems that snap together, nothing hard-wired.

Features

A whole loop in minutes — menu → timed dig → cash out → upgrades → descend, then again, deeper.
Seven ores, five rarities — coal to diamond, each with rising value and a brighter flash when it drops.
Four upgrades that actually change the run — more dig damage, longer dives, more ore per rock, more gold per haul.
Descend forever — tougher rock and richer veins every layer down.
Saves between sessions — gold, upgrades and best depth persist.
Juicy by default — floating text, screen shake, rare-find flashes and toast notifications on every dig.
100% drop-in components — no custom engine; it's a live stress-test of the Game Components pack.
Free — pay-what-you-want. Play it, then grab the pack if you want to build like this.
