SortofCuddlyFoot (my brother) and me, explosionsoundfx, have created an immense map filled with parkour. There are mobs, lava, arrow traps, the end, the nether, and much much more. There's also some redstone.
Score counter: There are 220 emeralds hidden throughout the map. Subtract the number of times you die from the emeralds you find, and that's your score.

Outstanding: 200
Great: 190
Good: 170
Okay: 150
:/: 120 or less
There are many interesting features:

Different colored paths for difficulty
Bed checkpoints
Sets of armor and weapons
Multiplayer support (multiple sets of armor and weapons)
Emerald score counter
A maze
A personality quiz :)
TNT, of course

I hope you enjoy! It is our first map, and we really want feedback.
