I'm afraid that's not possible. It would take so much time to implement, and I don't have that much time.
I mean, it's a free game you make in your spare time. You have no publisher to answer to. You can take as much time as you want. I'm not even saying it has to be in the next update or even anywhere soon or something, just eventually down the line. I can always bookmark this game and come back to it at a later point.
