In a hurry, but...
it just occurred to me that simply announcing that I had finished my latest KS level without posting a link to it was a bit stupid. So, you can download it here:
http://www.allabouthmpf.com/kslevels.htm
It's the last one, Remembering the City. If you've never played KS before, you also need to download the software linked at the top of the page, and you should probably play the very short tutorial that comes with it. That will teach you everything you need to play RtC. (In fact, you don't even need every skill that the tutorial teaches you to play RtC, because RtC is really easy - but you do need to know how to jump and double-jump.)
