Nice path! Took some time to figure out the right combination for 85. Happy to have found a secret passage :D Took me a long time to locate it. Drive like dada gawth is back and better than ever Solid puzzle with a couple of possible ways to trip up. Love this one! There are a lot of plausible routes, and it's amazing how close they are to each other. One of your best for sure. Really fun to work through this one! For quite a while I thought 105 was optimal. The 55 gave me a hard time Awesome solution! Lots of plausible paths to consider.
