WOW!!! I really think you have a HIT on your hands. No joke. I can definitely see this being like a legit mobile game that people would love! It's insanely clever!
However, I strongly suggest getting rid of the "lives." If you beat a level, it's beaten for good, and if you fail, you just restart that level.
Other than that, this is an award winner! It's so smart, it fits the theme in a way I could never have imagined, and it's addictively fun!
The little dice guys are so freaking cute too!
Truly, amazing job!
