Nebulus 2 is the sequel to the famous puzzle platformer Nebulus (aka Tower Toppler) designed by John M. Phillips and released by Hewson. The first game introduced a concept of pseudo-3d based on the "rotation" of the background.
If the predecessor, born on 8-bit platforms, was later ported to several other computers, Nebulus 2 was not so lucky in terms of distribution and never reached the fame of the first title. The sequel was born thanks to the initiative of two young German developers, that were not satisfied by the 16-bit versions of the first Nebulus. It was developed for the Commodore Amiga. Despite an Atari ST version being announced (and printed in the cover and manual), the game was released only for the Commodore 16-bit computer. Signed by Infernal Byte, Nebulus 2: Pogo a gogo was published by 21st Century Entertainment, founded by Andrew Hewson himself in 1991, once Hewson Associates was closed.
Amiga owners and fans of the first game were not disappointed since Nebulus 2 is better in almost every aspect: better graphics, better animations, and better sound. Pogo, the hero of the game, still has to reach the top of the towers (7 in this sequel), avoiding traps and enemies. But this time, there are many different levels and settings and several new "powers," including jumping boots, magnets, and rockets.
Reviews from the magazines were also highly positive; it's just a pity that this sequel didn't reach the first game's popularity.
