Ninja Remix is the conversion for Amiga and Atari ST of the Commodore 4 hit created by System 3, The Last Ninja. This action adventure is probably the best game ever created for the 8-bit Commodore platform and it sold over 750k copies.
Unlike Last Ninja 2 and 3, the original game was never released on 16 bit platforms until 1990, 3 years later. That's why probably they decided to change the name. Unfortunately System 3 also released a Ninja Remix for 8-bit platforms, which is an enhanced version of Last Ninja 2, so it's a total mess.
Anyway, thanks to the great work of Eclipse, and its main coder Marc Rosocha, Ninja Remix is the best game of the series you can play on the Amiga. It keeps the original atmosphere, great gameplay, music and in some cases, even bugs, of the C64 version, but with the graphics improvements you could expect.
