Pretty simple and neat. Not particularly random, but it's definitely a good game on its own regardless of the jam theme. I had a fun time with it. I was able to go through a couple of the levels no issue. I do wish the walking was a bit faster, but that's a minor nitpick in an otherwise really good game.

I think the game really fits the theme of the jam. All the tiles are faces of the dice, making mechanics predictable and clear referencing the well known object. Even the latter Lava tiles made mechanic obvious but tricky, as they are switching between the opposite sides of the dice. It is that "thinking outside of the box" that Mark was talking about.
