Astrea is a DICE-deck-building roguelike that flips the script on deckbuilders by using dice instead of cards and a unique dual “damage” system: Purification vs Corruption. Build a dice pool strong enough to purify Astrea's out-of-control corruption and save the Star System.
Rather than the traditional card-based approach, players build a pool of various six-sided dice in Astrea. These dice come in four "rarities" - Safe, Balanced, Risky, and Epic - each with a different balance of positive and negative effects on their faces. Safe dice have mostly beneficial results but weaker effects, while Risky dice offer powerful but volatile outcomes. Carefully curating this dice pool to find the right risk/reward balance is the core of the gameplay loop.
Instead of a standard health bar, players manage a Corruption meter that fills as they take damage. However, Corruption can also fuel certain abilities, creating an engaging risk/reward dynamic. Purification actions reduce Corruption and damage enemies, while Corruption actions heal enemies but damage the player. Strategically manipulating this Corruption/Purification balance, and moving between high and low Corruption states, is crucial to success.
Six unique playable "Oracles" offer a wide variety of approaches, from the aggressive Berserker to the cunning Spellcaster. Beyond just these base abilities, players can further customize their Oracle through a deep progression system of Blessings, Sentinels, and dice modifications. Discovering powerful synergies between these elements is a major source of the game's depth and replayability.
While the dice-focused gameplay may seem very random, Astrea provides players with substantial tools to manage that randomness. Abilities to reroll, discard, or modify dice faces give a significant degree of control over each roll's outcome. This encourages a gameplay loop of careful risk assessment and mitigation, rewarding players who can master the balance of chance and control.
As players progress, they'll steadily unlock new Oracles, Blessings, Sentinels, and other customization options, providing a constant stream of new strategic possibilities. The game's Difficulty levels can also be incrementally increased, allowing experienced players to continually challenge themselves.
