As I'm sure you're aware, this isn't the only puzzle game like this in the Jam. However, 1) it means that I was better at it than I expected, and 2) the level of polish here made this game stand out from the others. The dice movement felt great, and (while simple), the sound effect when you match gave me a good dopamine hit.
My only really feedback would be that I didn't quite understand the scoring or the timer. Sometimes I would get a score of 0, for seeming to do the same thing. And was the time connected to my score?
But you've made a very polished puzzle game here. Great work!
