Nice level-design! I really enjoy the minimalism of the puzzle. Each one of them is tricky, but with a kinda intuitive and surprising solution to find. I was afraid the core concept could become a bit dull, but the game is just long enough. My main issue was some confusion on the controls: I would often use the arrow keys to try to select a dice, or the space bar to validate my movement. ^^' But that faded away eventually once I got used to it. Overall it's a really cool entry. Well done!
