Mineheart Abyss [v3.0c] By ArcanePengi

Meet the Monster Girls
As Sapphire digs deeper, she’ll encounter rare resources and local cave-dwellers who are eager to help—and eager for attention.

• Tippy the Mole – She loves the dark, hates clothes, and is ready to get down and dirty to help you find some gems.
• Lumi the Slime – Sleepy but helpful, she’ll provide as much slime as you can hold. What will you use it for?
• Holly the Horse – Equipped with her pack of goodies, she can help you carry much more as you journey deeper.

Gameplay Features

• Satisfying Clicker Mechanics: Tap your way through layers of rock, uncover rare gems, and maximize your mining efficiency.
• Crafting & Smelting: Don’t just hold raw ore! Smelt your findings into precious ingots and craft powerful gear to dig even deeper.
• Hidden Treasures: Discover secret chests packed with valuable loot and rare upgrade materials.
• Underground Fishing: Need a break from the grind? Find subterranean rivers and cast a net to catch cave fish to feed Tippy.
• Lewd Loops: Build your relationships with the monster girls and unlock spicy, fully-animated loops.
