The game is fun, largely thanks to off-the-wall humor and challenging puzzles, which range from dealing with burnt pizza, portable cyclotrons, and alligator love potions. Most puzzles are quite hard, but fair. In an innovative touch that predates Legend Entertainment's games, Castle Ralf features a menu-based interface that you can use instead of the text parser: just select verbs from the menu shown at the bottom of the screen. This means you can see at all times a full list of verbs you need in the game - a nice touch that IF beginners will find helpful. There is also automapping: a map of your surrounding is displayed in the bottom right corner, and constantly updates as you explore. If you are looking for a harder and funnier fantasy text adventure than Zork, Castle Ralf is well worth your time. Two thumbs up, way up!
