The idea for this game is a good one. If the dice were thrown at the start of a turn in random directions and the fly had to change the numbers BEFORE hitting the ground, I could see the game being a challenge.

As it stands, the dice can be changed once they touch the ground, and the score/time limit mechanics don't exist. I'd like to see the game be finished, couple of sound effects put in, and the human players off-screen to make comments every time a favourable combo appears. I think it'd be funny to see them reacting to this fly rigging their game.

I love the idea of being a fly trying to rig a game of Yahtzee!! Makes me wonder what the people playing Yahtzee think is happening. Maybe it's a trained fly? Or maybe a hand would try to swat it away? Anyway, clever & creative premise!

Even without score system implemented, I found bopping the little dice around quite satisfying :) Hope you'll keep working on it!
