The princess seems a little rude sometimes (especially when you burn to death :O).
That aside, the game looks really nice and stylized! With a very creative idea. I also liked that your levels self-tutorialized the different blocks as they appeared. Wish there were more puzzles to play :)
In terms of accessibility, I wish there was a button to reset a level (before the knight starts walking) because on occasion I would swap on the first dice and immediately realize I messed up, but I'd have to swap twice more and watch the knight walk before I could try again.
