I'll look at adding community copies once this bundle for Trans Rights in West Virginia ends. If you're in Brazil, I have a deal on my website to get 50% off all my digital games. If you're in another country that you think should be added, feel free to let me know!
I'm not sure what you mean extend the play time or "traditional gameplay." You can play as long as you want to answer the prompts. Some people have managed to play over the course of a few months, spending hours answering the prompts. Some only spend a few hours playing. Take a look at the free preview on the page to get a sense of gameplay, and I think that should give you ideas on how you can lengthen time.
