I thought the dice movement felt pretty consistent! After a bit I got used to the idea of rotating and shifting the faces to orient them how I want, and it made sense that it was a representation of rolling a 3D cube (though I might be biased because I spent so much time figuring out the orientations of a rolling cube for my game, lol)
I think if you had more time to flesh this out, it would be good to have a few early levels which show the player different techniques for reorienting the dice, though what you have is really impressive for a jam!
