i mean like is the game going to required payment or not, like do i have to pay money or is it free
Oh, yes, Project Yuri will be a paid game when it's released on Steam, although it will come with a demo to help you decide whether it's worth it or not.
If you're asking about United by Love's Heart (sorry, in the end I wasn’t sure which one you meant), it will have an early access version that will cost money, but there will be a demo that will keep getting updated, and the final game will be free.
