Popular games for collection ASCII's Castle series

The object of the game is to navigate through Groken Castle to rescue Princess Margarita. The player can push certain objects throughout the game to accomplish progress. In some rooms, the prince can only advance to the next room by aligning cement blocks, Honey Jars, Candle Cakes, and Elevator Controlling Block.

The game has a fairly standard plot of rescuing a princess from a castle, though the game itself was considered very large for the time. It also contains a map system similar to that of later Metroid and Castlevania games. The Castle was followed by the game Castle Excellent.
