It's hardly important, but the playback doesn't work entirely accurately. For example my playbacks of 11th Feb and 15th Feb are wrong - they leave unconnected regions.

This might be related to me using Chrome - when I click to 'unshade' a square it sometimes flickers on and off rapidly instead of clearing (I'm also unable to reliably mark off used clues - I think that often a single click is treated as multiple clicks).
