I go fast I guess
It not the fact that there are to many enemies on the screen at a time, it's just N64 hardware is old and things don't run as fast as they normally used to.
Just did a run with your route, but died at the generator because I crash landed my plane and I had a bazillion enemies around me. I think going to the TNT from your way is slightly slower than going the normal way, past the mountain, as I lost 4 seconds to my original time, then gained 8, then lost 4 because I got my car jammed somewhere, so it was going to be pretty average either way
