Your idea is cool, but the game could definitely use more finishing touches. But we only have 48 hours so, yeah!
I like how the dice are thrown with physics. I also like how you use more creative kinds of dice, not just plain 6 sided one. (Is a two sided dice just a coin, hmmm?). Also it's playable in browser which is a huge bonus because I don't have to download random people's files :D
The perspective feels a bit funny though. Maybe if it was top down?
And it might be nice to add faces to the die and little pop ups to let the player know what's been rolled.
Overall, pretty solid entry!
