Really nice game, I enjoyed it a lot! There was a major cheating bug, though - if you place a die between to spots - it gets used as if it were two dice :D Made the game 100 times easier :)
I really liked how you did the dice roll in 2D, which looked cool! I was also thinking of adding the dice roll, but was struggling with an appealing enough rolling animation without doping 3D rolls. What you did looks real good!
