I think i know who hyperhopper is.

EoSD is pretty cool, still on of my favorite of the TH series. I don't know, I can control her slow (no, don't post fat Reimu images) movement better. If I hop onto other characters I usually get messed up by how fast they are. Remilia/Sakuya was an exception, I was actually able to control their movements pretty well even though they're fast.

Sanae feels to me like a combination of Marisa and Reimu. Not too fast, wide area of attack, and still pretty damaging.
