A fine idea, the first time I played it I didn't really get it. But the real meat of the game is choosing where to move based on the numbers of the dice adjacent to the one you will be moving to. When you start thinking ahead in that way getting a high roll just seems like a really pleasant surprise, and even a lower roll seems like a reward for being prudent and moving to a spot where you still get a valid move off a low roll.
Plus, I absolutely love that you made the board rectangular. If it was just a square, a diagonal move would be the best move every time, but this way diagonal moves are still strong, so you might still want to risk it even if the options after that are pretty high, but now to be optimal you only need a certain amount.
A deceptively simple game, I love this one.
