This is quite literally the first public release of HoS and it STILL includes hours of content for the player to explore. 'Work in Progress' serves an important purpose of letting the player know what to expect in the future, as well as provide indication of when you've reached the end of the current available progression (This is how sandbox works!).
I am not sure what you think early development looks like, but go through any games early in their development and let me know when you find one that provides as much content as HoS does in their 0.1 versions.
I play a lot of adult games on this site during demo and check back on public releases. Other then slow burn titles that take forever to update and games that never add the content in the next update I never see the dev put (wip) or (coming soon) in them. I don't mean to offend you, my honest opinion from the experience I have from games I followed is the dev's rarely add them soon if at all. I know you think different maybe you are working on all that wip stuff and it will come next. I play a game when it updates that still has a (wip) tag in the same place it was on the demo and this game is 10+ updates now. Hope you do add wip stuff first and finish out the 4 women story you have in the story now, before adding 4 more girls half done and forgetting to finish any of the wip there are now.
