Silver Software has released an iPhone and iPod Touch remake of C64 classic Nebulus.
Few games on this hallowed list of C64 classics can claim to have aged as well as Nebulus; John Phillips quirky little platformer-with-a-twist.
In this instance, 'twist' is the right word, as the basic idea was to guide little squat alien called Pogo from the bottom of a cylindrical tower to the top, via lifts, stairs, and doors, avoiding various hazards along the way. Presented in 2D, the game featured some of the best visual trickery ever seen on the humble C64, proving - if further proof were needed - that the machine was highly capable when pushed by wily British programmers.
Aside from the highly detailed sprites and eye-catching parallax effects, Phillips came up with a wonderfully original pseudo 3D technique which rotated the tower clockwise or anticlockwise, relative to your left or right movements. As you moved, Pogo stayed in the centre of the screen, but the impression of movement was brilliantly handled. A similar technique can actually be seen in one of Super Mario Galaxy's levels.
