Great aesthetic and music choice! I really liked the rolling mechanic, dodging around enemies as I tried to line up the right face to attack with was super satisfying, and I really liked the dice display in the top right. I also liked the tension of choosing whether to dodge enemies or try and hold on to the number I wanted to use.
I think enemies better telegraphing their attacks would be a big improvement. I also feel like having enemies spawn in discrete waves would give a better sense of progression. Oh and emphasising the result of the combo, maybe just with a little particle effect to draw your attention to the health bar, would've been a nice touch.
Was the reward for finishing the combo planned from the start or did you decide on it later in development?
A great and creative entry overall with a solid core mechanic. Good work!
