Im pretty sure Sinister uses Velcro with the second controller upside down do the D-pads are on the same side.

For good ending, you have to buy the health so you can buy the last map from the store. So easy isn't any faster. Easy is a cop out for a category that is meant to be a challenge. I'd leave it the way it is.

pld is all knowing wise DT2 mod. Get rid of Easy and have Any% and Any% hard. Runs for the later qualify for both categories. As for the "main" category, everyone knows that is good ending. Good ending is good. (yay on the question at hand)
