Oh, should've kept reading before posting what I just posted. Cool, glad to see it's him; nobody ever figured out if it was AI for the Percy Jackson one, and, frankly, having used the Siserg LoRAs on SD1.5 and on SDPony, it does a very good job of ripping off Siserg.Siserg is the founder of SinBeansStudio, and he is the lead artist for TeamSadCrab, behind Innocent Witches so that's why the artwork is in the same style.
Development of Innocent Witches in terms of story development/coding was not Siserg's responsibility so while I agree TeamSandCrab have a habit of dragging their game's development on without much progress, I would not attribute that to Siserg.
Curious to see how this turns out, but as it's a demo - not expecting much yet.
