Very fun and polished game with a very cool aesthetic (both visually and audibly). A few tiny changes I would make:
- make spacebar input act as a roll button for convenience, or have the game auto-roll at the soonest possible time so that you only have to focus on one thing
- make dice "roll" text only be displayed (or flash) when the bar is actually full (so that it alerts you when you can actually roll)
- having a cool moving background or something that matches the aesthetic might elevate the experience quite a bit
Overall, a great game.
