Why's this not included in your BL Bundle on steam?
Also is the Unity port still being worked on ^^ tyty
Yes, but the person working on the Unity port is a student, and right now he's busy with his college projects. He's already made a working basic system, but adding all the dialogues and making the calendar and dates to function properly will have to wait a few months.
That's the reason why the game is not included in the bundle: I prefer to keep the game on a low profile until everything is fixed. Right now the game is fully playable, but depending on your options you still might find bugs.
