This is Find the Chest, a gamemode somewhat similar to the popular Find the Button but within the infinite terrain of the Minecraft world. Twelve chests are hidden throughout the Overworld, Nether and the End; just twelve blocks will result in success, among millions of others. For each level, you must use a single clue that will lead to the whereabouts of the chest, and then bring back the diamond in each to the main base, where the next level will be unlocked. You also have a maximum of three additional hints across all twelve levels, so use them wisely! Note that each level only has one hint available, so if you're completely stuck, you may just need to spawn in a diamond to skip the level.
This is my first Minecraft map, so it may contain glitches. Any feedback would be great as well!
