If you get your kicks from those fairground rides that have you reaching for the nearest brown paper bag, then Melbourne House has got a treat for you. Cos, with Gyroscope, those nauseous thrills have been transported to your Speccy.
It all sounds very easy - guide a giddy gyrating gyroscope across 20 screens - just five courses of four screens.
But don't be fooled! The gyro's got a will of its own and you'll need to be quick witted if you're to stop it falling off an edge or hitting an alien, while manoeuvring steep slopes, slippery glass or directional magnets. Gulp! Pass that paper bag...
In fact, I really thought I had it cracked after belting through the first course, but it's all downhill - literally! - after that. Shame you can't pick a course at random to get a bit of practice on those stickier screens.
Melbourne House says a surprise awaits at the end of the game - getting to the end of the game would be surprise enough for me!
Gyroscope, with its stunning 3D graphics will have you hooked - especially if you're a devotee of Marbles Madness, its arcade twin. But remember to keep a bottle of aspirin by your side...
