Hi! My deepest apologies for the loooong delay. TL;DR: Life got crazy, moved country, moved some more, planning another country move this year.
However, I have slowly been working towards the Splash screen for Chapter One, in the form of designing the main star - Dr. Watson's pet box-er fish (yes, another pun), "pup". You can see the character sheet art on My ArtStation: https://www.artstation.com/artwork/vbdegO
Next step is to incorporate it into the splash screen.
Then move country again - but after that, the next steps are taking the Scene 1 background from Sketch to Polish, and making a "News" splash screen...
