## What is Umerun?

Umerun is a grid-based line-clearing block puzzle game. While keeping all the familiar fun of block puzzles intact, players take on a wide variety of tough puzzles across more than 100 stages, making full use of ever-changing stage conditions, exciting obstacle gimmicks, and special blocks that deliver the thrill of a game-changing comeback.

    【Basic Controls】
    - A board with a grid for placing blocks is displayed in the center of the screen.
    - Four blocks are lined up below the board.
    - You can place a block by dragging the leftmost of the four blocks onto the board.
    - When you drag a block over the board, the cells where it will be placed are highlighted.
    - The block you are about to place can be deleted (discarded) or rotated.

    【Rules】
    - When you completely fill a vertical or horizontal line on the board, the blocks in that line are cleared.
    - Clearing a line awards points and bonuses based on the number of blocks cleared.
    - As you place the blocks in your hand, new blocks are replenished one after another.
    - The game is over when there is no empty space left on the board to place the next block.

    【Block Types】
    - Standard Blocks: Blocks in various geometric shapes such as squares, L-shapes, T-shapes, and straight lines.
    - Villain Blocks (Bombs): Once placed, a countdown begins, and when it reaches 0 the block explodes and inflicts a score penalty. You can defuse it safely by clearing it with a Happy Block.
    - Happy Blocks (Rainbows): These appear only rarely. Placing one instantly clears the blocks around that cell and safely defuses any bombs within range.

    【Stage Design】
    - There are over 100 stages, with the difficulty rising step by step.
    - As you advance, the shape of the board itself changes into complex and unique forms such as L-shapes, donuts, and crosses.
    - Some stages contain obstacle cells where blocks cannot be placed, requiring strategic space management.

    【Rankings】
    - Supports Apple Game Center.
    - Your best score is submitted to the online global leaderboard, letting you compete with players around the world.
