Perhaps Luxee being able to revisit Parental Love will be a chance for them to recharge creatively. They don't seem to be creating updates as fast or as big as with A69 as they did with PL, despite A69 seeming to be a lot less work, at least based on dialogue and so forth. They might be in a bit of a creative slump or just lacking motivation with the game. I imagine it's probably draining as a creator to have to convey Nea's experience, while at the same time a large proportion of your fan base completely skips over the content.
Meanwhile, they seem to be multiple ideas for things they wanted to add to Parental Love, where I think fan support was more consistent. Until they get these ideas out of their head and into the game, they could be a roadblock or at least an impediment to working on A69. I don't imagine them revisiting PL again in the future, but at the same time ideas for a third game could begin to form. That's what happened during PL. when Luxee had the idea for A69.
