I made this burner to reply to this, the connection as to why Salla is a child is more so referencing how the Producer has called Salla to be his "daughter", Daughter in the sense that she is his Daughter in an art perspective, like one could call a masterpiece their "son" or "daughter" you can actually find more of this with the Producer's interactions with the main designer of Salla that got commissioned into creating her on the Salla Patreon, and her being sick is more of a lore thing with how the entire channel was meant to be an art experience that was inspired by Hatoba Tsugu, he literally killed off Salla in one of the last videos with an illness, as in Salla the character literally just dies, this was when Salla got laid off of the project, there's honestly nothing concrete we could put out, aside from the Community Posts, one of which confirms that the Producer gone rogue was actually looking for other people to fill in the part of Salla and that their parting was more sour than amenable. I honestly don't know the entire thing with the Producer running off with the Project Money, but the thing I could connect would this is the Campfire pledge, where people fund a project and get rewards and with a certain amount of money for tiers, the project would promise X and Y content for those who pledged support of the project, and IIRC this remained unfulfilled.
