We're working on another game set in the same world that will be similar. We're also working on another free romance game. You can see more updates about it here: [link]
To unlock the bonus, you have to get all the endings. There are two "alone" endings (one where you win, and one where you lose the best) that you need to get. The easiest way to get those is to focus on raising on stat the entire time. Save the game before you have to guess who Alistair is. Guess correctly for the win end, and guess incorrectly for the lose end.
