I don't recall a time when there was a fight AND a puzzle to solve. I think the game pretty much works that the respawning enemies will have to be defeated, or used to progress to a new spot, before you can move on. I don't remember the specific spot you're out, but is there anything you can hit the enemies into after Double H uses his special attack? The picture isn't clear enough for me to recognize the spot your in to offer my help.
I got stuck at a few spots, but in the end, I figured it all out. Hang in there. I know it's possible to have a glitched spot, BUT, if the creatures are coming, you probably need them for something.
