Very close to being perfect! I love the concept.
The only two issues I had were:
- I wasn't sure what face was which on the die when choosing the symbols: I see the top one changing in real time, but since it is rotated 90 degrees on the board model, I'm unsure if "right" is the face on my right, or on the die's right (which would be bottom to me)
- the lives are a bit too forgiving, since you can choose symbols randomly and still manage to pass each level. 3 might be enough to force the player to think a bit more about it's die. Either that, or maybe add a negative effect to draws so that it's not possible to breeze through a level by only avoiding defeats? Not sure.
But, apart from that, it's awesome! The art, the sounds, the concept, the feedback, etc... It's an excellent puzzle game submission! =D
