Holy Cow. How did you do this? Mc edit? or by hand? (If so your incredible)
MCEdit and WorldEdit/SPC, with the Build Commands mod added on (for the vine and erode tools). I had to do a little bit by hand though - blocking off other caves/mineshafts, the water coming from the ceiling, and of course the parkour itself.
Thank you guys for all of the replies and positive feedback. Here's a screenshot of my next project: (It's a CTM map this time. Sorry, parkour lovers!)
This map that I've started making is going to be big, so it will likely take me a very long time. During that time, I probably won't be working much on parkour, but if I'm feeling up to it when I finish, I'll begin work on Just Jump II. Even if I DO make Just Jump II, though, it won't be released for a VERY long time (basically, however long it takes for me to make The Painter and JJ2 combined).
In the meantime, if you want to see more stuff from me, feel free to play TSC (link to is at the bottom of the original post) or Just Sprint (at the top of the original post). Thanks for being patient!
@crazygoattoe: Nice LP, but I don't think I'll add it to the original post seeing as I have enough LP's already.
