Pac-Attack, released for the Game Gear, is a puzzle game that combines traditional Tetris-like falling block gameplay with the classic Pac-Man characters. The game was originally released in 1993 and challenges players to align blocks and ghosts in a way that allows Pac-Man to gobble up the ghosts when he comes into play. It's a unique twist on the puzzle genre that integrates the familiar chomping mechanics from the Pac-Man universe. The game is known for its addictive gameplay and was also released on other platforms such as the Super NES and Sega Genesis.
