i really like the concept of the game, i don't think i've seen any other game yet, where one of the goals is to reroll dice by launching other dice at them.
but very important: i did take me quite a while to understand the actual concept of the game!
i think you could've made the way the dice interact with eachother more explicit, and that it would've helped make the mechanics clear.
generally i prefer tutorials that teach you by playing, rather than reading about how the game works.
i would've enjoyed some rolling sound effect for when you roll the die
also i think the volume of the music overshadows the soundeffects a bit, but the music really fits your game well!
another important part for me is that this game genuinely is quite fun
good job!
