I feel like there should be a time w/o loads extension in this game. After watching GameguySD stream attempts, I noticed that his load times are a lot slower than some other times. I have clipped a load time from his stream, as well as one from my current PB, to demonstrate how this makes a big difference to the overall time of the run.

These loads could end up costing a run, it doesn't seem like much, but for people with slower load times it could end up costing 3 to 5 minutes.
