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?

Good game, can kinda maze build, the water is annoying tho
This is without a doubt, one of the best td games on steam. It's got the same things that made the original gem td on warcraft 3 custom great, plus far and away better replay-ability and options for both mazing and single-line defense. If you're worried about the price, the demo should tell you if you want to invest the money - I put at least a dozen hours into it, and actively dug through my steam inventory selling cards and even picked up CS2 for drops just to get it. It's worth it.
im sure there is a really great tower defense game in here. but i was so confused after playing the tutorial i thought 13 dollars was too much. the art is great... the dev seems engaged and is active. but i will need to pick this up again when its under 5 bucks.
Very nice game, countless small touches that give the game a nice polished feeling. Demo data can be carried over to the full game, so give it a honest chance.
It is a very engaging maze building TD game. Very relaxing at lower difficulties and a real challenge at latter ones. I'm having tons of fun, so far, experimenting with different gems. My only real complaint is that i feel there's a lack of augments to spice up the runs. There's only a handful of them, so a higher number of whackier, run defining augments would make it as much of a roguelike as a run of lets say Binding of Isaac or Slay The Spire. But this is a great game either way!
The game hits a good spot for tower defense fans It is complex but not too complex. There is variety in maps, augments and gameplay And it has a free demo, so just try it out if you are interested The only downside for me is that there is no permanent upgrade system, just unlockable miner classes
I like this game, the optimizations possible are actually kind crazy, and the way that there's a few different methods of acheiving near-infinite scaling is pretty great! I've had a lot of fun, and within the first like 10 hours i managed to make it to the top 5 on the endless leaderboard. It's not necessarily a hard game, but it certainly has a lot of replayability. Plus it's a steam game, so y'know i got it pretty cheap
The children yearn for the mines
very reminiscent of the Gem TD custom maps from WC3 and Starcraft 2, a good spin on it.
Great game, great dev, come relive the old GEM TD days from DOTA
