A new kind of deckbuilding roguelike. In Lost Pages, you don't draw cards. You draw elements. Instead of drawing cards randomly, spells require elemental resources such as Fire, Water, Earth, and Air. Every turn, elements are drawn from the pool created by your deck, creating a completely new strategic system. This unique mechanic was recognized for its originality at the Google Indie Game Festival. Draw Elements, Not Cards Each spell requires elemental costs. Your deck determines the element pool, and every turn you draw elements randomly from that pool. Managing your elements and planning your turns becomes the core strategy. A new twist on the classic deckbuilding roguelike formula. Ether - A Unique Element A special element called Ether adds another layer of strategy. When drawn, Ether changes its nature instantly and always triggers an additional element draw, sometimes creating powerful chain reactions. Mastering Ether can completely change the flow of battle. Build Your Deck Discover and combine a wide variety of: - Magic Circles - Artifacts - Runes Every choice changes your strategy and opens new possibilities. Create powerful synergies and build your own unique deck. A 5-Act Roguelike Adventure Explore a roguelike map where every run is different. Face powerful elites, deadly bosses, and unpredictable encounters as you progress through the world. Challenge 100 Levels of Hazard Beyond the main adventure lies the Dimensional Gate. A special mode with 100 levels of escalating difficulty, designed for players seeking the ultimate challenge. How far can you go? A Mysterious World Lost Pages takes place in a unique universe centered around the birth of the moon. Experience original story animations and uncover the mysteries of this strange world.
