You and your Uncle Silas live in a crumbling mansion. Silas keeps sleepwalking, and it's your job to guide him back to bed and away from anything which might wake him up (everyone knows that if you wake up while you're sleepwalking you instantly go as mad as a train). Naturally, there are plenty of threats to Unc's somnambulism [Whoa! - Ed].
Sadly, the house is filled with lethal things getting in Silas' way. There are live elecric cables around, piles of drawing pins, trap doors, very loud radios and other things. If you can't gently steer Silas away from these, you must set them off yourself.
This soon becomes incredibly painful for you but it will have been worth it once the old man croaks and you get all his loot. That's got to be worth a few burns and broken bones, eh readers?
The game is done in a sort of 3D and you're torn between setting off the traps and keeping up with Unc on his wanders. It's quite difficult to juggle these, and I must say it's rather a lot of fun. There are loads of rooms in the old pile, and plenty of visual jokes too. Sleepwalker is another weirdie from Zeppelin. But this time it's a winner.
