I like the concept, it's actually a pretty tricky puzzle game. There are some flaws in the execution though. A clearer grid would have been or an easier way to tell where you would end up on your next move would be useful. As of now, it's very hard to tell at a glance where your going. I think it would make more sense for the die numbers to be on the direction you are going instead of where they are relative to the die. That would just make it more intuitive even though it doesn't make much sense.
It's pretty interesting though overall, good job!
