Loved the soundtrack! Combined with the clean visuals, the reactive sound-design, and the neat transitions, it provides a very playful mood.
This kind of puzzle can feel a bit tedious at time, but I like that this game provides some "hint" on how to solve levels. Especially in the later ones, if you're attentive enough, you can guess which path to take to clear the level. This is good level-design! There are still some cases of "fiddling randomly with the dice until I find the correct number", but not as much as in other entries of the same genre. The downside is that, for some level, "solving" feels just like "following the instructions", but it is less frustrating than being stuck, and still satisfying to see the solution unfold itself.
The end credits are also a cool addition. I see there's a unused mechanic. I guess it's a good thing to have avoided too complex puzzle with it, but it's still a fun surprise to discover it at the very end, with a last small conundrum. Overall it was short and pleasant. Good job!
