Found sort of a middle ground on gameplay style. I do stick around a bit longer on each level, but not quite as long as I used to. I try to run a zigzag up the middle whenever possible with the occasional side to side when there is a predictable spawn area for soldiers. I managed to get into most of the POW camps this time, but avoided the ones with the arrows in the wall booby trap as I have a hard time with those. I have not ever been able to hit the POW spot by the airplane even with a good deal of effort.
Blew up two bunkers this time, that was tricky and I lost a life the first time I tried, but got both of them my second attempt.
Found a really good strategy for the final gates at the end of each round, you can either hang out at the top right or left close to the gate opening and just mow everyone down who comes out. This is harder to do on the very last level (for which I lost 4 lives).
Made it all the way through the game one time and died in my first few steps at the restart.
