Hello! I recently bought an xbox controller to play games with and was so happy to see you have controller support! (I added it to ours also). This was a decent entry with some rough edges that could easily be polished. First I think you need some pulsing game music for when doing the lap. I also think you need some way to see which snowmen you've already hit as you go round. Next there is the controls - the sensitivity was off with the thumbstick for aim so I tending to use the left thumbstick to move into a firing position instead.
Anyway, despite the rough parts, the fact you delivered all this on your own in your first GWJ is _very_ impressive - my first attempt was not up to this standard!
