Yep, the dice switching was meant to be a major element. Sadly we got caught out at the end and weren't able to bring in our core mechanic or any tutorial in time. You were supposed to have an inventory of dice in a menu, so you could pick the one with the desired possible effects before each shot, giving a puzzle element to the game of deciding which die is most likely to be best for each shot. We'll be pushing an update after the jam to restore the game to the intended format!
