If Tetris and Pipemania had a love-child, it would be Droplitz. The game has players creating paths for drops to flow through. Drops which successfully flow to a U-shaped piece get added to the drop counter on the left while ones that don't are wasted. When the drop counter reaches zero, it's game over.
Players control the game by rotating tiles with different shaped pipes on them. Once a complete path is created, a purple droplet drips from the spout towards the bottom. When it reaches its endpoint, all regular drops in the path get added back to the drop counter and the tiles corresponding to the complete path disappear, making room for new tiles. -
