Lab Escape is a puzzle/adventure map made originally on the Xbox 360 version of Minecraft and now converted to 1.7.10 on the PC.
It has tons of challenges, from parkour to mind puzzles, using many elements of minecraft's game mechanics.
The PC version now has added command blocks for spawn rooms, faster circuits and more Easter eggs.
