I think the problem is 0.7 is the Emily "pure husband" route, and he thinks not many people like that. I don't think he likes it very much. But, in a game where you can choose to be on the Emily route, it needs work, like all the others. Given that 0.7 is solely an Emily route (announced when 0.5 was released, or shortly after), it can't really be made better.
You know, people said the same kind of things when Mr. Dots announced Melody, and DMD was in limbo. Turns out Melody is really nice. Maybe A69 will be. Maybe not. But we won't know until it's released.
PL is coming to an end. Sure, not in the next few updates, but the end is in sight. Luxee needs something new to work on, and needs to start on it before PL ends. That's how things work in this industry.
I think the big problem with Emily is her hair. It makes her look old. She's gorgeous, but that white hair just doesn't work for me. I still like her, tho!
