Wobbly, wacky and welcome is Wunda Walter. This is a funky, nonsense game requiring aeronautical skills and an aptitude for executing telling belly-flops. Guide Walter in a flight across four distinctive, scrolling landscapes, swooping down to the ground to steam-roller small, evidently offensive globes then lurching into the stratosphere again to avoid prickly vegetation and abrasive rocks. As you soar over hills and valleys, keep an eye out for marauding balloon-bustas bearing in mind that erupting volcanoes ain't too healthy for wind bags either.

The title screen depicts the four regions which are to be your stomping ground: a red volcanic region; white icy wastes; a tropical sector; an arid yellow desert.

Soundwise? The Yellow Rose of Texas is the opening fanfare with good supporting sound effects scattered throughout the program. It is possible to wave goodbye to the Flying False Teeth of the first screen and face the cyan balloon-poppers of the polar regions simply by picking up easy points: there is no compulsion to stick your neck out, or whatever balloons have instead.

Overall, a first rate, fun game full of colour and even a scrolling commentary. Not suitable, however, to those who prefer their close encounters to be of the deadly earnest kind.
