All the others, have fun.
The first few moves are the hardest, since it looks like there're so many ways to go. Choose your way carefully...
Note: there MIGHT be more than one unique way to solve this. Soon after making it I forgot the solution, and was just happy to re-solve it AND write down the solution, so I didn't do an exhaustive search for other ways. Besides, it's "just" a crumbling maze -- who cares if it has more than one solution anyway?
All bridges are 1-step.
