Java Edition 15w14a

15w14a is an April Fools' joke released on April 1, 2015. It was released as a hoax announcement for 1.10, which Mojang named The Love and Hugs Update (unrelated to the actually released update). No further snapshots were released for the hoax update.

Gameplay

 * "Love" meter
 * Appears like the health bar, only across the whole top of the experience bar
 * Fills up when the player takes damage or left clicks on mobs
 * Resets upon quitting the world
 * Collecting eight lines of hearts unlocks a game called Minescreeper, which is Minesweeper textured like Minecraft
 * On the top of the screen is the Minecraft logo, with "CRAFT" crossed out and "SCREEPER" written over it.
 * The game contains a grid of grass block tops, which when left clicked become dirt blocks with the numbers depicting how many bombs are touching that block.
 * The size of the grid varies based on the GUI scale, and the game resolution, though the amount of creepers remains the same. At the default resolution and GUI scale, the grid size is 8×25.
 * The flags from Minesweeper are replaced with signs, which can be placed with a right click
 * The mines are replaced with creepers. Any creeper that was marked with a sign has their mouth upside down.
 * Pressing the keys, , , , , , in this order (just like the classic Minesweeper) will  play the level-up sound and activate a cheat that shows if a square is safe or has a mine under it with a white square in the top left corner.
 * Winning the game or placing a sign before the first left click triggers the credits, which upon exiting returns the player to normal Minecraft.
