Played this numerous times including the Halloween version and found it enjoyable. I like the multiple paths robots can travel through and the control point that opens a shortcut gate I believe (some missions don't use it at all).
I like the details like the swaying trees, lore written on a billboard, the sea's horizon, and the intricate brushwork that bring out the best in the London pack. I'd definitely study Whitecliff if I made an English themed map.
