A really solid foundation for a full release here.
I loved the simple style and I think you could easily make a full game out of this with a few more ideas for mechanics. Speaking of which, I am suprised you managed to make so much content in just 48 hours!
I kept placing the pullers the wrong way round (pointing towards the dice instead of away) but that's just me. I think how you have it set up is the right way to do it.
Overall a really great game. I would definitely play a full version.
