It took me a while to understand that I was swapping the faces of the die with the floor - I thought I was just slotting the right face down and winning. Still, once I figured that out, it was a nice surprise! Now I understand the name "splicing dice"
This was an interesting idea. I found that the die often did not roll the way I wanted it to - perhaps my camera was off, but I think if my cursor raycasts to a face, it should move in the opposite direction to the FACE, not relative to the camera. Aside from that, it was a good game with some interesting ideas. I got too frustrated in the 4th puzzle and gave up haha, but still you should be very happy with this product!
