Obviously getting more art and CG and sex scenes is always a good thing, but is obviously a bit slow going due to only being able to get a handful every update. Something I would really like to see that would make a lot of improvement and can move along a bit faster is getting small things like the descriptions for the research topics, workshop rooms, and hints/goals in the portal room. Those are small things, but are kind of jarring when some things are just blank.
One of my favorites and I always look forward to what's coming next.
