Echoheart
A downloadable Echoheart for Windows, macOS, and Linux
Echoheart is an action roguelike, turn-based deckbuilder hybrid, with a cyberpunk meets cosmic horror vibe.
You carry an Echoheart—a parasitic biotech implant that lets you freeze time itself. When combat erupts, stop the world and use echoes to chain devastating attacks, then watch your enemies crumble as time resumes.
