I thought the aspect of hitting a dice to make another one move, the golden one as well, pretty fun and I could see it develop into an interesting mechanic, almost like a play of pools where you would hit a dice into another for maximum killing efficency. Those ennemies at the start spawn a bit too fast and close to the golden dice, and maybe an indicator to see when we could send our next dice would be nice for future builds (like a small animation of the end loading up, or a simple bar charging, anything)!
