Hi F0Xx,
Thank you so much for your kind words! We're so happy that you enjoyed the demo, and overjoyed that you've called it the best visual novel you've ever played.
As for your questions, we plan for it to be around $29.99, and it will be out early 2021. Yes, it will launch on both Steam and Itch!
If you want to keep up to date with announcements, sneak peaks, etc. you can follow us here on Twitter. We've put up a lot of previews lately, too!
Thanks so much!
