Roguelike deckbuilder where you climb a procedurally generated spire, fighting enemies by playing cards from a deck you build run-to-run. Each ascent starts fresh: pick cards after battles to synergize with your strategy, collect relics that modify rules or grant passive bonuses, and choose branching paths with different risk-reward profiles. Combat revolves around managing energy, drawing the right cards, and exploiting enemy patterns. Between fights, you'll encounter events and characters that can help or hinder your climb. Death sends you back to the bottom with nothing but knowledge of what works. Success depends on recognizing strong card combos, knowing when to skip additions that dilute your deck, and adapting to what the spire offers each run.
