Not this game
Last Epoch has a Woven Echo item and a season conversation that shares almost none of the letters’ intent with this platformer. Mistfall Hunter’s cipher puzzles show up beside “weaver echo” queries. The Sims 3 has a mod sometimes styled Echoweaver. SpiritVale has a card with a similar name in several languages. Ball x Pit has a boss called The Echo Weaver. Overwatch’s hero Echo, and the 2017 game ECHO, still occupy some question boxes.
None of those products share a save with Moonlight Kids’ game. A code, a build, or a patch note from one of them will not open a door in Provenance. If you wanted the 2026 time-loop game, stay on this site. If you wanted a different Echo, the name in the paragraph above is the one to search on its own.
