Developer Notes
project_haydee - is an action-adventure game based on Unity (yes, I do this, and it's just work). It will give you what every original Haydee player wanted. And even more, because this is not only porn, also a game with its own story. I plan to add more erotic content, implement a gallery system, and introduce new gameplay mechanics. Stay tuned for updates!
