Lovely explosion effects! And kindof cathartic with how many dice games there are (myself included, hah!)
I think scaling the explosions would be great. That way you could avoid trying to match a "6" down... without actually getting it down to a 1. i.e. you blow 10 1's, maybe that explodes a 3-wide ring around every 1? I don't know if that would actually improve things, but maybe a neat idea to consider :)
Otherwise the learning curve was easy to understand. Well done.
