Awaken to a realm where dreams and reality blur beyond recognition. As the Awakened One, you must traverse a haunting world of nightmares and fragmented memories, where nothing is certain and every shadow hides unspeakable truths.

Navigate through twisted dreamscapes filled with abhorrent creatures that defy comprehension. Master brutal combat, unlock arcane abilities, and forge your path through interconnected levels where each step forward reveals deeper mysteries about the nature of existence itself.

Help tormented souls uncover their buried truths while questioning your own reality. In this dark gothic horror experience, the line between salvation and damnation rests in your ability to distinguish what is real from what is merely another layer of the endless nightmare.

Built with ZEngine, a custom engine crafted from scratch using C++ and SDL3. Special thanks to the SDL team for decades of dedication to open-source game development, providing the foundation that makes projects like this possible.
