Tap an edge to open a valve. Tap again to flip it. Again to close.
Open valves move 1 unit per beat, the way the arrow points.
A cell over the line for 2 beats cracks. Gone for good.
Hold a cell to seal all its valves.
Converters turn one color into the next, all of it, every beat. Tap one to change which. Converting grows grey scale. Scale past 4 slows it to 1 a beat. Six Flux in it scrubs scale.
Do what the glowing cell asks. Every win grows the machine.
