ECHO ROOM: Time Puzzle

Your most important partner is the person you were seconds ago.

ECHO ROOM is a time-based puzzle game about recording your actions and coordinating with Echoes that replay them in the next loop. Every move becomes part of the next timeline, until several versions of your past self work together to complete one solution.

■ COOPERATE WITH YOUR PAST SELF
Record movement and device interactions. In the next loop, your Echo repeats those actions. Hold switches, open gates, route relays, move crates, and cross hazardous rooms in exactly the right sequence.

■ 10 LABORATORIES, 100 TIME PUZZLES
Master 100 handcrafted levels that introduce new rules step by step. Begin with focused temporal experiments and progress to complex laboratories that demand precise coordination across multiple timelines.

■ CREATE A BETTER RECORD
Earn stars by completing each experiment with fewer loops and fewer moves. Finding a solution is only the beginning; every timeline can be refined.

■ TURN FAILURE INTO A CLUE
Progressive hints and recovery guidance help you understand what went wrong and plan your next attempt without taking control away from you.

■ PRIVATE 2–4 PLAYER CO-OP
