Well, in the first version of the level there was a backroute, and this route was similar to the route of the Havoc 5 challenge.
But with the three pixel deep gap in the terrain I made this way impossible.
I think Arhibar is thinking of this route.
Anyway, Conway is with his route, as I supposed, very close. You only need to shave off a few pixels to make the miner survive. Have a look what skills are left after executing your route, and then use one of those at a certain point in your solution. I think now you should be able to find the full solution.
