I really like the overall gimmick of this app. When I downloaded it it was more for an "eh why not I've got too much time on my hands rn" thing. To be honest, I wasn't expecting it to run smoothly and genuinely thought there'd be a lot of bugs and such. But nope! To my pleasant surprise it runs very well so it actually makes easy to use.
The artwork used in this is really well done for a free app of this scale. I also really like the diversity that can be achieved; as a pretty heavy, curly haired trans man, it's almost impossible to make an avatar actually look like me. But I managed very well with this app!
