Development may feel slow in part because this is only about 1/4 of what we do. We balance it out with animated content and work on other games to keep a variety of supporters happy.
Hiring people is also difficult - with the nature of our work the best hire would be a 3D animator to help on that side, however to find someone who is talented in animation, willing to work in daz studio, willing to do NSFW content and willing to work for someone else is extremely rare. Most people with that combination are already creating their own content.
That being said, we have just released version 0.3 last week on Patreon. It has about 3-4 times the content as the free version and by being available to supporters helps with production costs (like hiring more people where possible).
