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.
Just bought the game today after playing around with the demo, took me a while to finally decide to get it. And now ngl I'm a little disappointed. I understand however that the demo was more polished than original I just hope the game is still being worked on
Edit: Also great game very unique take on these game, on playing on android for now still a big difference between demo and and paid. But if the money helps progress the game I'm all for it. And if it gets better I'll likely get it on my PC
