It's quite a good game. The visuals and overall concept are cool, and the mechanics are easy to understand. I think there's a lot of potential, even if it feels a bit unbalanced at the moment.
As for the gameplay loop, it works for me. It's really satisfying when everything starts bouncing around and eventually turns into some crazy numbers. However, it doesn't seem very easy to actually get a build going. You only have a limited number of dice, and some relics simply don't do anything if you miss.
I think there could be more radical synergies between the dice and relics. Not just ways to make the numbers bigger, but more interactions built around collisions and chain reactions. The one shown in the GIF feels really good — maybe the game just needs to make moments like that easier to set up?
It would also be great if the dice had more visual identity. Right now they all look quite similar, so I found myself checking them one by one to remember what each of them did.
