Thanks for reviewing it. Agreed, we would have liked to polish the game a little more, refined our controls and explored different, larger levels. We had a couple of hinged walls that would flip around when the dice rolled, but we couldn't get them working with the rolling die in time so we removed them.
Jack was always our main character, but we were also planning on spawning the other characters inside the dice throughout the game, so they could be collected for bonus points or rerolls, or injure you, or just be physics nuisance.
