Not the most unique mechanic, but good execution! The art style is nice and I liked the humor!
The other dice also behave in interesting different ways... But unfortunately all the enemies in the first 2 screens lined up perfectly for me to just roll through, so I only understood the mechanic once i got to the castle xD And one solution to beat diceula is to just walk up to him and then back some steps, so that seemed a bit too simple (even though I only noticed that on my third attempt)
