well the twinning one was a commission, and although we'd love to focus on it more, it is a bit of a logistical toughy for the game to handle. it just opens up a lot of complexities that we weren't intending to handle from the get go, even if we just use the same assets twice X3
that said, there has been a lot of enthusiasm for it! so it may be something we look into later on in development if we have the time!
