So, I just bought this today, its a very unique game and I would love to be able to play it, even the demo on the website runs better than my download...tl/dr below
 and it has several issues, I am not able to save, its very buggy, it literally has only like 1 position to do per "turn" and it very much feels incomplete It advances day by day but it always repeats the same dialogue and she only switches  locations from couch to kitchen. However when I visited the website for the creator of the game it shows a very different gameplay and screenshots and they seem to be keeping up with updates and everything....is there something wrong with my download? How can I get help?

I've been preparing for a major update, most issues with the current build are a result of partially implemented features. Next release will have everything + new content.

As for positions, click the positions button in from behind and cowgirl for alternate positions.

Itch does not get unstable development builds, only more stable development releases. It's just been taking a long time, sorry.
