Love this one. I think if the maximum digits were lower, the game could be a lot more fast-paced. I was only able to get through 2-3 cars when i tried to get them all to 0 miles, and its unclear if it would have been better to go through more cars with higher mileages than fewer cars with low mileages. It might be better to just have the player focus on getting to 0 or near 0 instead of asking them to consider if they should cut their losses on higher mileage vehicles. Great job!
