i think neither are impressive, but both are cool. the only balancing act that impresses me would definitely be the mission to mars solution.
i just dont get how that works. if we dont lose momentum on flat surfaces, than it would be impossible to remove all momentum while making it to the balancing point. because if it runs out of momentum on the hill, than it should roll back down. if it has momentum, than makes it to the tip, the only flat pixel, than it shouldnt lose any more momentum while on that point. theres no air resistance in this game, so ???????
because im pretty sure that a ball will roll forever on the flat.
