Okay so this is confusing hehe
Put all the frames in order (which I'm sure you did ;u;~)
on all the frames add 'Frame' and them name them Frame 1, 2, 3 etc ;u;
The first frame add just (100ms) and on every other frame just add (100ms)(replace) no spaces
To speed it up , lessen the number, to slow it down just make the number higher ahah ;u;
its a little tedious but it works hehe, I hope this works!! ;u;
could I use this as a icon?
