You made this game in less than 3 hours‽
I love the concept—it's extremely creative—and it's easy to see how you'd expand on it with different shapes/requiring the orientation to be correct. Maybe if you had it so the dice sped up, that could provide for a good difficulty curve. The darkness with simple lighting is nice.
This game was quite fun after I got the hang of it (I got to 50), but I had a bit of trouble figuring it out at the beginning (I was trying to put the dice backwards + the tutorial text disappears quickly). Perhaps if you had more time to develop the game, a visual tutorial might be a good addition (but of course with less than three hours, that wouldn't be a priority.)
Also, thanks for the Mac support + explanation about how to get around security features, it's much appreciated.
