Yes, they used the PC Genjin 2 graphic engine, it suits the Amiga version with all these pastel colors and a better looking player sprite. Well, the sound is better imho, a mix of old PCE tunes and some new Amiga stuff. But the best thing is the gameplay, the controls are a bit smoother. Sadly they never ported part 2 and 3.
Anyway, Dynablaster (Bomber Man) and Parasol Stars are direct PCE ports, pretty good ones too.
