What if a game’s most useful upgrade lived in the player’s memory? In Unity’s new developer interview, Moonlight Kids describes Echo Weaver as a time-loop adventure where learning the world unlocks progress, without conventional ability gates.
That premise still needs careful state management. Some discoveries survive a reset; temporary events do not. The team separates persistent world geometry from a lighter scene containing the player and run-specific systems, allowing the latter to be recreated when a loop ends.
The useful design lesson is to decide what a reset means before building every interaction. A shortcut, a carried key and a remembered conversation may each need different rules.
For an AI-assisted prototype, we would start by writing those rules as a small state table, then test two consecutive loops. That is our proposed experiment, not a technique the studio says it used with AI.
