Unknown Echoes

Still in development, feedback is welcome. The current content is primarily focused on the first dimension, "Echo Realm." More dimensions and abilities are planned for future versions, with an expected total of 3 dimensions, 6 main bosses, and 5 abilities/artifacts.

Step out, listen to the echoes of the earth, and discover a world long forgotten.

Unknown Echoes is an adventure Mod centered around exploration, puzzle-solving, boss battles, and progressive ability growth.

You will open the gateway to the Echo Realm, tracking ancient echoes across ten distinct biomes, solving ancient mechanisms, defeating guardians, and gradually mastering three "Echo" powers, ultimately completing your personal "graduation" at the Cliffside Grand Archive.
