According to Patreon, it's more like they've been done writing for it a long time ago.
Last time I checked they're focused on music and art.
Well... that and a Sonic game I don't know much about.
There is indeed a Sonic game (a remake of a certain game) that I want to make, albeit I keep that under wraps until I actually have something worthwhile. No use if I publicly make an announcement right now.
And yes, music and art is being done. Art depends on how much time the artists have which was less time lately. So I use the time I have for a Gallery function right now.
