This is an awesome concept. I found myself shouting the numbers to hit while pressing the numpad.
Some background music would have been nice, as well as maybe a little bit more feedback to things, like rolling or running into the ketchup(?) or other obstacles.
I do love that you can just roll off the table or backwards, and it seems that you can make your dice jump up as much as you want. I didn't test enough to see what happens if you keep going at it though, but I wonder if you can avoid getting captured by the mobile hand.
Thanks for the submission, I enjoyed it!
