CATCH NOW. REMEMBER LATER.
Echo Keeper
Move the amber paddle with pointer, drag or Left/Right. Its blue echo repeats your position exactly 1.2 seconds later. Amber pulses need the live paddle; blue pulses need the echo. An amber/blue pair shares a destination but arrives 1.2 seconds apart. Read upcoming pulses and preserve your history.
