{STEAM_CLAN_IMAGE}/43688931/db5c735f7fa2813dc18dc5ae2e25e20f29b431f0.png Are you ready for this new chapter? I've been working on Idle Cave Miner for over 4 years now, it started as a hobby project that I worked on when I had some free time. I never expected much of it, but 4 years and 1.5 Million downloads later, it has become my full-time job, which still doesn't feel real to me. When I first made ICM, I had no idea how a game should flow, what made a good idle game, what elements players like, how to design progression, and many other things. These past years have been a big learning experi

As of right now, Idle Cave Miner is Free to Play on Steam! Rewards for players who bought the game should also be fully rolled out, to receive them, either restart the game, or press the red 'restore purchases' button at the bottom of the in-game store. If, for some reason, you're unable to claim your rewards, please reach out to me as soon as possible, you can message me on Discord, or send me an email to pedro@coldhours.com describing the issue. I look forward to seeing you all on the mines! ~Pedro

Hello fellow miners, I would like to start by thanking each and every one of you for playing Idle Cave Miner, and for leaving both positive and negative feedback, this process is essential for me to keep improving the game. As you're probably aware, the game didn't have the best launch, not because of bugs, but because of a series of bad decisions from my part, and for that, I would like to profoundly apologize. The main critique was the fact that the game was paid, and still had MTX, which is a very fair argument. In hindsight, I should've released the game as Free to Play, and modify the sho
