There really isn't anything to criticize. The visuals are appealing; the music is fun and bouncy; the gameplay is engaging, and the idea is completely unique and intelligible. This game was polished across all dimensions. The only thing I can think of is that it may not hit the theme completely but I'm uncertain. Sure, you've got a six-sided dice but then again the mathematical term and its solution could be interpreted as two sides. Anyway, this shouldn't concern you, your submission is of top quality, great job!
