Ember and Blade

Survivors-style action against endless hordes, with long boss fights and a dark story. You are a demon hunter lent immortality for a while by an angel's pact, walking into the realm where the archdemon Asmodeus has been sealed for centuries. There you meet Ariella, the only guardian still watching that seal. It plays out in runs: you cut through fields packed with demons while bullets fill the screen, and when you fall you start again. Angels hand you blessings that reshape your powers, so every run plays differently, and the bosses are tough and ask for patience, Souls style. LINE Games Corporation makes it and publishes it. There is a demo on Steam, and this is its second version. It has no date yet. It is coming to PC, with Spanish text.
