Ghosts and Castle is a classic arcade-style game for Android that takes players on a thrilling adventure through a fantasy world filled with zombies, ghosts, bats, orcs, and other horrid creatures. The game's main character is a knight on foot, dressed in plate armor, who can run, jump, climb stairs, and use various types of weapons. The game is primarily horizontally scrolled, but it also proceeds upwards at times. The player can walk, jump, crouch, climb ladders, and use ranged weapons. The game is protected by a plate armor, and when hit the first time, the player loses a heart, and when hit the third time, the player loses a life.

The game's difficulty level is high, and the appearance of the Game Over screen is far from infrequent. The player can lose a life instantly in some cases, such as when rushing into water or when time runs out. Some enemies carry jars that contain bonus points, weapons, or even new armor. All weapons are shot horizontally, with unlimited ammunition, and the player can get new weapons from the jars, replacing the previous one, but always in the same order. Enjoy the vintage arcade-style game and defeat the forces of evil with Ghosts and Castle, optimized for the unique smartphone gaming experience.
