Our Game is Not Going Well

Our game is not working out the way we wanted it to. One thing is, that the whole class hasn't got their back button to work. Another is that me and my partner have so much to do, that we can't decide which one we are going to first. My partner and I just finished getting our next buttons all to work. Know we have to and tween to our game, and a bunch of other stuff. I hope who every reads this is not having the same problems as us. If you have any tips of suggestions, please tell me.
