About

EchoShift

Read full description

EchoShift: Clone Strategy is an original time-based puzzle game built around strategic planning and self-cooperation mechanics. Instead of controlling a character in real time, players pre-plan a sequence of actions and then launch a time simulation. Once the timeline finishes, a clone is created that repeats those exact actions in the next round. By collaborating with your past echoes, you can activate switches, unlock paths, collect energy cores, and solve increasingly complex spatial puzzles. Each level challenges your foresight and efficiency, requiring careful coordination between multiple timelines. The game features five difficulty tiers, warm-toned Q-style visuals, smooth animations, and satisfying chain reaction effects when clones cooperate successfully. Every level clearly displays objectives, action limits, and success conditions. Designed for iPhone and iPad (iOS 15.0+), EchoShift offers a fresh, thoughtful puzzle experience focused purely on logic, creativity, and strategic planning — with no gambling elements or misleading mechanics.
