Great game! I love the overall vibe of the simple and clean art style along with the very smooth music. The puzzle mechanic is certainly creative and let on more depth/interest than I initially thought.
Hitting the number on the middle module exactly created some weird behavior I didn't quite understand (Like going from a 7/7 round it would display 7/8 but then adding a 4 would set it to 3/8 instead of overflowing or setting it to 4/8)?
Overall though, it was a lot of fun just playing around and figuring out the optimal play to survive without losing dice.
