Messes with the original's pitch perfect platforming in a pretty significant way, for the worse. When you input movement in a direction, there's a split second where you're locked in place, before you start actually moving. Why? It feels bad, and ruins the fluidity of the original. I guess it's not the end of the world when you're mostly moving right, but why would you make a change like that? It ruins the movement that makes the original so special.
