Cool concept! Also great that you turned his game into an online game :) I think it would be cool if the delays would be shorter and maybe you could control the game with keys alternatively. Also, another thing is that if the required score for the next stage is 1 or less, I think it could roll automatically. There could also be other things added such as having cards with more or less than four max dice. Or having influence on other players (if more than one is playing). Such as giving a player of your choice (or even all of them sometimes) a yellow card or make them skip their next turn or make them take a move back or something. Just some ideas :)

Thanks Hippo, nice ideas for improvements. This is still in the making and the next task for my grandson will be finding flaws and improvements ... Then maybe back to cardboard, wooden men and dice.
