Thanks for the feedback ! The game now tracks your progress and the small asteroid are now silver and hopefully easier to spot.
Im not completely sure what do you mean about the momentum.
Is it too fast ? Do you need a max speed ? Is it too slow ?
Oh and the game actually takes your death into account, if you fall more than 5 times, you loose 1 gold ball. I suppose that is too high a number, i'll look into that.
