This remake of the platform title from 1987 replaces the graphics and sounds
with new assets, while maintaining the simple gameplay of the original. The
player controls Zub, an alien armed with a laser pistol in a mission to
retrieve a powerful artifact for his Emperor. The main objective of each level
is to reach the top elevator, by riding and jumping into a series of platforms
while shooting the incoming waves of flying enemies. Once Zub climbs into a
platform, he can move it sideways to reach a better position closer to the
other ones, and keep climbing the screen by switching platforms this way until
finally arriving at the topmost lift tubes that gives access to the next
level.
