Just a quick note, the rabbit seems to be running rather awkwardly. The head only moves up and down with barely any horizontal/circular movement at all. What little of that movement it does have doesn't seem to correspond with the rest of its run cycle. Forelegs are acting funny too. Consider using more bunny-run references.
More things I spotted afterwards: Ears are straight, don't move at all (I suspect this will be fixed by the final ver.), and the low amount of frames is very jumpy. More frames would better suit the game's style, as the animations would finally catch up to the exceptional graphics slym has already proved promising with the latest WIPs. (Aside from the given critiques, of course.)
