They spent a while working only in the other VN, Temptation's Ballad. But both projects are alive and repeat in particular is getting updated art.
I don't know if you know this yet, but in a way work has technically resumed on repeat, but not with new story content . Apparently, all artwork in the entire game is being reworked , from the Sprites, to the CGs. Basically, the entire game is getting overhauled, art wise, story-wise, again no new content there just yet. Nobody really knows when it's supposed to be made public if at all, but I heard it's supposed to be quite soon. Fingers crossed
