Obby: Mine, Build, Launch

So you start with a basic pickaxe and a tiny plot of dirt. Your goal is to mine down through increasingly tougher layers of rock and ore, hauling everything back up to sell or process. At first you're just clicking -- left click to swing, right click to mine faster -- and watching your coin count tick up. But after a few runs, you'll unlock the upgrade shop where you can boost your mining power, carry capacity, and even the speed of your base's auto-refinery. The loop is simple: mine until your inventory's full, return to base, sell or process, spend coins on upgrades, then dive back in. What makes it click is the rhythm. You break blocks, collect glowing loot orbs, dodge occasional falling debris, and keep an eye on your stamina bar. Later levels like the Magma Caverns introduce heat-resistant materials and enemies like rock golems that slow you down. You'll need to upgrade your tool to a Drill or a Jackhammer just to make a dent. The satisfying moments come when you've saved up for a big purchase -- say, the Auto-Smelter -- and suddenly your passive income triples. Pets like the Ruby Slime or the Digger Dog follow you around, automatically collecting nearby drops. Skins are mostly cosmetic but some, like the Miner's Helmet, actually increase your light radius in dark zones. The difficulty ramps up unevenly. Some layers are easy pickings, then suddenly you hit Bedrock and need three upgrades in a row to break through. That's where hiring workers pays off -- they keep your base running while you focus on the next big push. Controls are straightforward: WASD to move, RMB to mine. On mobile, a joystick on the left and tap-to-mine on the right. There's no story here, just numbers going up and new tools to unlock. The endgame is about efficiency -- minimizing trips, maximizing ore value, and watching your empire grow from a single shovel to a fully automated mining operation. It's not deep, but it's loop-y in a way that makes you say 'one more run' a dozen times.
