I really enjoyed the game.
I like this take on the golf genre. Using the eyes of the dice is a clever way too show how many flicks you have left.
I would have liked some music, sound effects and better graphics, but you already know that, and I’m glad you spent most of the time on the gameplay.
While golf is clearly the inspiration, I think the game would be better if you didn’t have to wait for the dice to stop completly. I found myself clicking in frustration for the dice to stop. One idea could be to say that if the dice’s speed is below a certain threshold, you still get to flick the dice.
With all of that said: This is great for a first game jam game!
