I could be wrong but Neko Paradise is like a side pet

project and Alorth only works on it so often. I've always assumed most Alorth does is the models and animations, maybe some of the art, for the projects he's either partner or being to do. I've heard Perverteer ships a bunch of animation lewd orders and Alorth is pretty quick complying. Again, we're not inside the development of Radiant but Dammed seems to be most at fault here doing the coding and writing the story.
This is a part of a discord conversation about Radiant:
"Ferkill (05/29/2022) - It's almost summer and we still got no Radiant.
Sir Damned (05/29/2022) - Yeh like I said a couple weeks ago it's almost done. Couple more animations and a few batches of renders and we're gold.
It actually prob would've been coming out around this time if not for a small problem that occurred tbh.
But s'all good, people waited this long so it wont kill them to wait just a little bit longer.
Ferkill (05/29/2022) - Okay then, trusting you guys.
Sir Damned (05/29/2022) - Yeah you'll be playing it pretty damn soon, I don't wanna say the exact day just yet but it's in sight
I could prob guess, but
Not worth it."
Apparently coding and game text are done, and only graphics are missing.
