Really interesting concept !
The visuals looks neat & the music fit really nicely with the ambiance of the game.
The random position of the dices make for an interesting challenge but the jump could be a bit stronger/higher to compose with it. (most time you cant reach the dices & have to re-roll several times)
The movement also felt a bit zippy for a platformer but still playable.
If you want to iterate on the game you could introduce new mechanics in the leves as you go : moving enemies , several dice zones by levels, having to climb up a level with one big zone & several bells.
That could add some more challenge as the levels start feeling a bit repetitive a bit fast right now.
All in all it's a pretty solid entry with potential. Good job :)
