Their only other game, as far as I know, is Meltys Quest which didn't have battle fuck and had a corruption system that wasn't as deep as Karryn's Prison. Meltys Quest did have tons and tons of defeat CGs and sex events. They could be making a sequel for that game?
But yeah, remains to be seen what their future plans are, I've been checking their Discord everyday and they've gone mostly silent apart from the usual good mornings and answering bug reports. We can only wait and see for the upcoming reveal.
