Quarth is a puzzle shoot 'em up that was initially released for the arcades before being ported to a number of systems such as the Famicom, Game Boy and MSX2. The gameplay can best described as a mix of a vertically scrolling shooter and Tetris. You control a ship that moves along the bottom and shoot tiles at incoming groups of blocks to give them a rectangular shape and make them disappear. Each level scrolls at an increasing speed until you either reach the end or a block reaches the line floating above the ship.
TaoTao improves on the previous run by nearly 16 seconds thanks to rigorous subframe RNG manipulation, making the game generate the simplest chunks to complete.
