Portal 2's PeTI is really fun!
I imagine that part of the fun of this would be to watch others try to complete your maps. So do you want me to record myself failing over and over while trying to complete YOUR map? Send me a PM with the details of how to find your map on the Steam Workshop and I'll upload a playthrough to post here (just don't expect a running commentary from me, I'm not much of a verbal talker even though I like to type a lot).
EDIT: Dripik (Old Nile) made the following map,
although why not go play it first before watching me?
