Lock'n'Chase
Lock'n'Chase is an action game released in 1981 by Data East Corporation. Players control a character navigating single-screen maze-like levels while collecting items and avoiding pursuing enemies. The gameplay involves strategic movement through corridors, with the ability to lock doors to temporarily block enemy paths. The joystick controls movement in four directions, and players must clear each stage by collecting all items while evading enemies that become increasingly aggressive. The game features multiple progressively challenging levels with different maze configurations and enemy patterns.
