I don't think this ever pop-out as the question or information regarding the sound effect of HOVER DASH. So I'll put this one as bug instead, that.. the hover dash over water have sound effect of the normal running dash, IT'S WEIRD.. I think the developer forgot to add or even don't care about the sound at all.. (here I thought that for every song and sound effects on NGS is made brilliant-diamond quality thing). Sigh..
Anyway, the post has been sent! I'm hoping for the change
