Thanks so much for the reflective comment! It definitely leaves some stuff for thought. It's a great idea with relating gold multiplier with boost amount and might be something we'll look into adding in a balance patch after the jam. While the treasure run segment is not something we'll remove, it might make sense to reduce the brake-amount (or even remove the braking altogether) so it doesn't feel like a setback.
Thanks for playing and the great feedback, it's definitely something we'll take into consideration! :D
