To be honest, making a multiplayer game for a jam where most people will just be rating games on their own is not the best idea... at least make an AI opponent. In terms of ease of use, quality assurance, whatever it's called, I would suggest not having the game close after every finished game, and maybe putting the instructions in the game itself. Maybe clear up the rules as well, because the color of the square seemed completely random and independent of the dice number. I wasn't ale to understand it, sorry.
