this is MindOfFur most recent tweet (posted the 30th of June):
"Finally, got the confirmation I passed all my exams successfully, 2 months of summer to work on Scribbles' route, here I come! Right after Tate and his stupid amount of sprites are done being implemented..."
So... in a nutshell? We didn't receive any update because he was busy with both school and writing Tate's route. But we should expect his route to be available quite soon, and if I had to guess, we should receive it in the middle of july maximum (if adding the sprites become more chaotic than trying to keep Tate in detention). In the meantime, he is going to work on the 4th route.
