I thank you for taking my suggestion and adding a random character select in roster aswell as fixing those bugs, great work!
Luckily, this time I bring only some recommendations and only visual bugs to report, don't worry. These features could be included in 1.2.0 with the sound effects & music, or if you want to add these as a separate update, that's fine too.
Some key bindings for the main menu would probably be great, like arrow keys control what fighter you're hovered over, space selects the fighter, backspace unselects them, etc.
This is a bit of a meh suggestion, but maybe make the random character selector icon be a bit more distinct from characters who don't have a picture yet? Or possibly put it in a more unique place so it stands out more? Like I said, a very meh suggestion and very well can be discarded when every fighter has an official icon.
Noticed this when playing in Fullscreen mode, Iggy's Male icon is cut off very slightly by the black bars (example image below), even not being in Fullscreen mode, it still cuts off. Not entirely sure on how you would fix this, but it just a little something I saw when playing, that's all.
I recommended this in my first ever comment, but I'll say it again in case you forgot; The "FIGHT!" text when you start a match lasts for not even a full second, maybe making it longer would make it seem more natural? The fast transition of it is a little weird, I won't lie.
That's all I have for now, like I've said many times before and I'll say it again, sorry about all the long comments.
