The point & click interface is wonderfully easy to use! The name of an object automatically appears under the mouse cursor as you point at something interesting. Left click to walk over and look at it, right click to "use" it. This could mean anything from picking up something to put in your bag, to opening a door, climbing a tree, talking to someone, etc. Once you have picked something up, you can then drag it to another object in your bag or on the screen, to use them both in combination. Use the mouse also to move around on the screen - click somewhere and Hugo will choose a suitable route to walk there. Alternatively, for those that like a challenge, use the command interface by typing simple phrases for Hugo to perform, such as "unlock door", "talk to man", "look in cupboard" etc. and move around using the arrow keys.
The Trilogy includes all three episodes and the 30-page hint/answer book which gives the answers to all the puzzles in all the games. The Windows version retains the command line interface or the original DOS version, while adding a new point & click mouse interface, MIDI background music and digital sound effects (with a sound card), full online help and puzzle hints. The toolbar gives access to common functions such as the inventory, save and restore games, music and sound effects, help, "turbo" button and room descriptions.
