Very nice concept. Even though our games look very different, the concepts are pretty similar. If you choose to develop this further, I would suggest some UX changes that I think helped the feel of what I did when I implemented them.
More than anything, bring the concept of the reference die closer to the player. I've found my eyes darting left (to the player) and right (to the reference die) a lot when doing the movement math. If you could make it happen all in place (perhaps by highlighting a field you can go to in each direction, and maybe go a step further allowing the user to calculate the next move from that field (i hope the image explains it). This would make for a much more direct movement experience.
Good job on completing this in 2 days. I've had fun trying to collect coins.
