Hello, Fouzi!
I found "Happiness" series by a chance. My first game in the series was "Twilight Observer" by a Hopeful light. I played this game and... my heart has melted.
The way characters acted and music sounded was beautiful. After that, I bought the bundle and by the now I has finished the Milker game.
I am glad to hear about this Universe. Thanks for it!!!
By the way, I'd like to listen the Existence OST.
Is there an opportunity to publish zip of Existence music?
If so, I'll appreciate it!
upd 1: I found music in the game files ^_^
