I want to download the game, but I don't see Download button anywhere. Where is it?

“Since Midnight Chaos is a thank you to the fans of the series, I wanted to make it available who support the Sleepless Night series in some way. If you've created fan art, fan fiction, a translation of one of the games, or something else or have provided me with resources for the games and/or helped me with programming/art/testing, just send me a message and I'll send you a link to the full game. Of course, you can also create something new, it doesn't have to be super complex, just something small is good enough. I'll post fan art and other things on my website and link to a page of yours if you want.”

My first played visual novel in 'Sleepless Night'. After playing I am become a very big fan of visual novel and 'Sleepless Night'. But.....I am still  a school student and 15 years old . But I want to help for having Midnight Chaos. I will try my best to help you . I also start to make visual novel . So Marcel Weyer grant my request.
