Stack

Controls Goal: drop the block that slides left and right at the right moment to build the tallest tower you can. Controls: tap the board (mouse or touch) or press Space or Enter to drop the block. The first tap starts the game. Rules: only the part overlapping the block below stays; the overhang is cut off and falls away, so the tower gets narrower. A tiny misalignment (about 1 or less) counts as Perfect - the block snaps into place and the width does not shrink, and consecutive perfects raise the sound one note at a time. If there is almost no overlap the block falls off, you lose one of your 3 lives (hearts at the top left) and a new block comes out on the same floor; losing the last life ends the game (a slightly off landing costs no life, it only narrows the tower). The block gets faster as the tower grows (full speed from about floor 35), and the side it starts from alternates each floor. Score and ranking: the number of floors stacked (the base does not count), higher is better. There is no time limit but the block keeps moving, so there is no pause. Tip: follow the block with your eyes as it passes over the tower and tap near the center; when the tower gets narrow do not rush - one perfect drop restores your rhythm.
