I'm going to have to say that of all of the games I have played L-Dis
still stands out in my mind as the hardest game I have ever played. It still the only game I
ever had to resort to "cheating" to beat. By "cheating", I'm talking
about using the "slo-mo" feature on the Turbo-Joystick. This was the *only* way I was ever
able to beat the very last segment of the shooter... it's a segment where you
are flying though a tight tunnel (side scrolling), with what appears to
be a mesh covered with plants I think, scrolling full-screen between your ship
and the camera at a different rate of speed than the background and tunnel. And all of it was
moving screaming fast... Even with "slo-mo" the level was tremenously fast
and it was a very close call on finishing it.
...it warped my little mind. ;p
