It lacks a bit of polish, for example, there should be more borders on the first levels (it took a while for me to get used to the player character disappearing after going offscreen). I'm not sure if there is no sounds, or if I couldn't hear it, but it sure should have some. The screen aspect got a bit weird and it was difficult to see sometimes, might be a bug, I don't know.
Now for the core mechanics, it's pretty fun! I like how you need to think fast in some levels, because the inertia won't last long and every movement must be thought beforehand. As for theme, I do see the references for dices in the text, but it didn't really stand out for me in terms of narrative, aesthetics or gameplay. I guess it's passable for the sake of jam themes, but maybe the power ups could use different dice shapes or have the player character change the face side of the dice according to how many power ups it has. Anyways, way to go!
