itch.io

It should run entirely in the browser, as long as javascript is enabled for the site. Maybe if you have a different browser you can see if it works there. 
This is the first I've heard of a black screen issue so I'm not really sure what else to suggest.

Hey thanks! As far as ideas go, if you've played any of the "open world" styles of cyoas where you can freely move between locations, I think that would be interesting to try. I don't know if combat would really add much, but I've at least considered rpg mechanics like usable stats and inventory. There's also potentially switching to a dating sim or rpg maker format, which might complicate things a bit.

Ultimately I'd want to tell a story and build an interesting setting, while allowing the player to enjoy the sexy side of things. There is a story to the lab that could be further explored, but scaling the  core idea of tailoring the experience to your preferences does turn into a lot of work when I'm writing 4-8 possible outcomes to each scenario. I also don't think it would continue to be a bad end simulator, I like the idea of continuing after being changed.

Oh, tfgames.site would be the url just so nobody gets sent somewhere sus. 

I haven't ever actually made an account there, so I'll have to give it a look!
