FragMiner

Without any introduction or explanation, you see a character standing on a ledge inside a mine with a bomb in his hand. You throw it at a stack of ore to break it apart and make it fall onto the platform below. You get to throw several bombs, either by clicking or holding down the button, and the run ends after moving the mouse cursor over the ore to collect it. This is the main gameplay loop you'll be going through. After each mining run, you return to the hub, where the ore is automatically turned into gold that's used in the skill tree. As is always the case with incremental games, you start with a single skill or upgrade in the middle while everything else remains hidden to preserve the element of surprise. When you buy the first skill, you'll reveal all the others connected to it. This process continues as you purchase more skills, gradually uncovering larger parts of the tree. Some skills can be purchased several times, with each upgrade costing more than the last, but none of them outstay their welcome because they usually cap at around three levels. Maxing out an upgrade doesn't reveal any hidden skills, so you don't have to spend money on something you don't need right away, although you'll eventually want to unlock everything since even a single upgrade can make a significant difference. The first upgrades include stronger bombs, a wider mining area, increased chances of spawning more ore, and guaranteed gold after each run. Later, they unlock new ore types, including ones that help you mine more efficiently, such as sulfur, which explodes, or shrapnel ore, which fires projectiles when destroyed. The skill tree is a respectable size, but some upgrades remain locked behind the prestige system and only become available after you've prestiged the required number of times. Prestiging requires a large amount of gold, and while it resets your entire skill tree back to square one, it also grants a collection of permanent perks, such as more bombs to throw and different variants, a larger mining field, increased ore value, and several other bonuses. Each subsequent prestige becomes much more expensive, but you'll also earn gold faster, especially if you focus on increasing ore value. The downside is that you have to repurchase every individual skill after each prestige, which can become tedious. The good news is that this ends after the fifth prestige (2-3 hours) when you can unlock and purchase the entire skill tree, as well as access the Core Rift. This functions as an endless mode where you continuously throw bombs into the mine and progress through waves filled with increasingly durable ores.
