About
Roguelike mining meets autobattler with a TD twist, offering endless build variety! Mazing, gem merging and roguelike elements collide to create chaotic defenses and wild synergies. Gem Miner TD puts you in the role of a crafty miner tasked with creating deadly mazes, combining powerful gems, and surviving relentless waves. Every run feels fresh, unpredictable, and filled with dazzling chaos.
Craft Your Maze - Most TDs make you build around a path. In Gem Miner TD, you dig the path.
Huge Gem System - The Gems ARE the Towers. Discover over 60 unique gems. The more you merge, the more powerful you become!
Roguelike Perks - Experiment with over 80 Augments to stack buffs, enhance gems, empower your miner, or alter gameplay mechanics for a unique build every run.
Endless Replayability - With 4 unique maps, 9 Miners (classes), over 50 mob types, countless gem combinations, and powerful augments, every run is a fresh, exciting challenge.
Easy to play, hard to master! Colorful pixel graphics, deep strategy, and endless replayability await. Climb the leaderboards, unlock the Vault to further customize your build, and push your limits in Endless Mode. Are you ready to maze, merge, and survive… or get dragged into lava, freezing water, or maybe the poison pits?

I put way too many hours into the demo and I'm going to put even more now on release.
Reminds me of GemTD on Dota Definitely what I needed
Wow, amazing TD, not much more to say. if you like TD´s with mazing and a A LOT of interesting Towers --> buy it i played a LOT of TD´s in my 43 years, this is definitly one of the best
just an amazing homage to Gem TD. Besides that, it's a very very clever tower defense, with lots of possibilities and really good replayability. If you like tower defenses, this is definitely a must try
Heck yeah!
Very fun TD with multiple play styles. Not your average TD in the sense you can put towers wherever you want, but fun nonetheless. Feels rewarding to get a working play through going with towers, augments, buffs, and enchantments. Lots of replayability. Looking forward to updates!
good game! reminds me of elemental TD from Warcraft RTS nostalgia hit hard
buy
