Neat idea! I appreciated the addition of the little cheat menu to the left to allow players to explore the mechanics, and I liked the mechanic of collecting and assigning more of the classic polyhedron dice as I went to apply to the player's abilities.
I felt like the jump height threshold on the platforming was a little high for how sensitive the jump is to being held down. I also think it might help to add some inertial damping to the pips when the enemies drop them, as if you don't collect them immediately they continue to slide away from you and you'll have to drop down to pick them up if they fall off the current platforming section you're working on. Overall, nice job!
