As an aspiring animator, I can tell you that animation needs to be a time-consuming process that requires concentration and the best effort you can possibly give.
This website is actually insulting. I mean, can't we just DRAW characters? I thought the point of animation was meant to be your own drawing coming to life, not some badly-made little sprite that moves for you.
Go!Animate claims that they're "teaching" kids how to make animations themselves, but they could at least, AT THE VERY LEAST, let us draw and use actual dialogue, not some awful Microsoft-Sam-style speech recognition thing.
I could go on and on and on about the many flaws this site has, but it's easier to simply advise you to stay away from the site, don't bother using it, and if you DO decide to give it a go, DO NOT actually give money. There is a Premium option, but all it seems to offer is extra options for making your characters.
