#2This is great. Simple to get, not too simple to solve. One I will share with my kids, plus now introduced to Julia Robinson festival. Thanks for sharing.

#3Better challenge: generate these puzzles in a way to have a unique solution.

#4Are these always solvable? The handful of 4x4's I've had don't seem to be.

#6Knowing that a typical maze will have branching paths at the beginning, but necessarily one good path at the end, I find it easier to start from the goal and work my way backward.

With arbitrary generation rules they are surely not. This is a counter example on 4x4:
| 1 | 1 | 1 | 1 |
| 1 | 3 | 3 | 3 |
| 1 | 3 | 2 | 2 |
| 1 | 3 | 2 | G |
| 2 | 2 | 2 | 2 |
| 2 | 2 | 2 | 1 |
| 2 | 2 | 2 | 2 |
| 2 | 1 | 2 | G |

I did about 10 4x4s and 6x6s and they were all solvable.

Worth noting, since it was absent in the rules, that it is unnecessary to touch all of the squares.

#10The wording isn't good. The number does not indicate how many jumps you need to make. It indicates how far you need to jump.
Otherwise fun!
