I finished in 42:42, I guess this is a perfect score! =D
The physics is pretty well done. A bit slow, I wish there was less cool-down between each dash, but globally the platforming is very solid. The big issue I had was that I was always confusing the jump button for the dash one, and reciprocally. Honestly I think they could be the same (since one action can only be done on the ground, and the other in the air). The less buttons to memorize, the better!
The presentation is neat too. I like that minimalism. And the dynamic audio on the dice actions is pretty satisfying. Well done!
