I played Last Ninja too! It was tough in some parts but I liked it. I recall the music was good too.
My favorite from those times:
Good music too. A couple years ago I played it a lot again. Got to a point where I could achieve black belt almost every time. It looks a bit insane to play this game on an i5 and a 27'' monitor
I know International Karate. I especially played IK+ or IK2, not sure about name, it was fun playing human vs. human! Also awesome graphics for the period and another great game by System 3.Â
In Last Ninja, when I was playing long ago, I never got past second level and even achieving that was a miracle. But that was when I played floppy version, before that I played pirated cassette (Turbo 250) version in which levels could be loaded separately. Good times!
Now, another great tune and one of the first shooter games I played - Commando.
