There's some great mechanics here, like the brake having a "stamina" bar, picking and choosing where to put pegs. I personally would prefer even more control over the outcome, like a permanent, less effective brake, or a button you can press once per turn to cut the momentum in half. Fantastic stuff for your first game jam though, i was impressed by the background, the performance bonus feature, how the score races up instead of updating instantly, "combos", etc. Lots of stuff that takes time and you don't always think about
