Ah, Game Over :) . This one came with my 6128, in the same disc that contained Camelot Warriors, Phantomas II, Dustin, Don Quijote, Abu Simbel and Nonamed. I played it a lot back in the days and I remember that I managed to master the first part. The second was a different story though, so I actually never managed to finish the game. Those shields made my life really difficult :-X
The title is a very good summary of the game. Hard as hell, the first load can be completed easily, but the second is very difficut because the ground mines are a paint in the ass. And the final enemy is unbeateable unless you do the trick.
