Retromine is a deckbuilding roguelike strategy game that challenges players to survive dangerous subterranean expeditions while managing a growing collection of cards. Created by developer ccdg and featured in the “Finish Your Game” Jam in early 2025, the title emphasizes difficult decision-making and efficient resource management. Players must strike a careful balance during their runs; mining scorium is necessary to escape the collapsing caverns safely, while mining ore is required to purchase new cards and upgrade the deck for future attempts. The gameplay loop focuses on the cycle of digging, failing, and improving. As players tunnel through the pixelated abstract caves, they collect various resources and utilize over 50 different tool and action cards. The experience is designed to be highly replayable, with procedurally generated content ensuring that no two expeditions are exactly the same. Mastery comes from discovering powerful synergies between cards and learning to exploit combos that can break the game’s difficulty wide open. This design encourages a “flow state,” where the challenge aligns perfectly with the player’s increasing skill level. The full version of Retromine will be available on Steam Beyond the mechanics, the game offers a distinct atmosphere centered on relaxation and focus. The visual style uses a classic retro-pixel aesthetic involving 8-bit graphics, paired with over 40 minutes of hypnotic synthwave music composed by Airglow. This combination creates a meditative environment that contrasts with the intense strategic planning required to win. Since the game serves as a demo for an upcoming full release, the difficulty is notably high, asking players to test their problem-solving abilities to the limit. Accessing the game is simple for those looking to test their mettle immediately. Players can play Retromine fast and easy on kbhgames.com for free, directly in the browser, with no installation reduced to a minimum. While the developer plans a full Steam release in the future, the current version allows anyone to jump into the mines and start building their deck right away. Whether you preserve your run effectively or perish in the caves, the goal remains to refine your strategy and dig deeper next time. The controls are simple to learn: General: Esc = Pause, Left Shift = Show hotkeys Expedition: Left click = Play cards & interact, Right click = Reorder cards or cancel, E = End turn, D = View deck, A = View draw pile, S = View discard pile Shop: D = View deck, G = Start next expedition, R = Reroll Retromine rewards patience, deck management, and careful decision-making. Winning is a challenge, and players who manage to reach the center will know they’ve truly mastered the system.
