It's alright, I don't mind a few extra comments here and there from him. He's reminded me about updating some of my stages before and I honestly appreciate it.
I reached out and asked Milla's creator, he currently doesn't have plans to make her a playable character. However, if someone wants to, they are free to use the sprite from the recent buddy as a starting point. I can't speak for anyone else though, but Milla getting in is a possibility, even if small.

Hello, sorry to be back here. This is to.aedan's parent again. I told him that I'd ask if anyone knows how to ask Milla's creator if there are plans to upgrade her to a playable character someday. I'm sure the suggestion to create the mod Aedan's self was a natural one, but it's way beyond his means. But he's very worried about about her not being playable. I don't play so I don't know why it matters, but he's - well if you could point me in the right direction I'd be grateful. Thanks for your time and any help.

Did Aperson say he has a new character coming out next month? That "new character" he was talking about is going to be Milla Basset

How about we have Milla in Rivals later - wouldn't that be fine?

Parent here - very sorry. Won't happen again.

Ugh! You've got to be the kidding me!

She is in Rivals! Just look at the stage thumbnail lol

In all seriousness though, he's not gonna make a character just cause you keep asking. I suggest you learn how and make Milla yourself.

Aperson! Please, please, PLEASE! Get Milla Basset into Rivals! PLEASE!

Speaking of Milla, now we're really really really really really really really really really really really really really really really really really really REALLY desperate to have Milla Basset in Rivals!
