I've been trying to complete a run of Story Mode without pressing right on the Control Stick or D-Pad. I've been able to reduce inputs to around 4-5, but one I think is very possible the drop. The only remaining inputs are from the very first level, before you are able to access the Sword enemy. At this point, the only moves I can perform are jumping, pressing left, flying, and air dodging. Does anybody know of a way to get momentum to the right without a copy ability?

You might be able to try sliding as normal Kirby in the start of the level, although I'm not sure if that involves pressing right. Being hit by enemies could also work, but you would have to get into a very specific setup to do so.
