Really neat level. Spent a while looking at two potential paths and trying to think of a way to optimize them, and then eventually found an additional path that was somewhat different from both of them.
Another nice simulated annealing level. Took me a little while to figure out, but the solution sort of falls into place piece by piece as you realize what needs to be done.
Very nice level. Surprisingly difficult to even get to the end, especially for a Highschool level. Optimization is pretty minimal after you get there though.
