Its quite fun to play and while I was mostly doing random things and following level design clues in the beginning by the end I was able to use a few techniques to solve them quickly. I think the first levels were good at conveying mechanics and goals. I was a bit thrown off by the layout in the bottom left until I figured out it was based on the button I pressed and not a flattened out die.
I do wonder how many submissions will have similar concepts though. This is the first one I've run into at least and I liked it.
