Three Seconds Behind
A grid puzzle game where an echo repeats every successful move three seconds later.

The idea
Every successful move is queued for an echo to repeat three seconds later. A move made now becomes a tool for changing the board after the player has moved on.
Design
The player and echo can both trigger pressure plates. Later puzzles combine that delay with crates, phase floors, patrols and paired rifts. The next-action indicator shows when a queued move is due.
Build
The Flutter prototype has twenty chambers with eight levels each. It supports guest play and keeps progress on the device when cloud access is unavailable.
