Nice game. However, I think you could give more thought to dice prices and abilities. From the lower cost dice, there is basically no point to throw anything except for 3 cost die, since it provides most points with minor risks (worst case - you lose 1-2 points. And i couldn't save enough points to through 200p dice in the 10ish minutes i have been playing.
Having a more clear understanding of what type of results can different dice produce would be great too.
Overall, nice time killer, but there is still room for an improvement.
