Neat game, and great presentation! I really liked the little inventory pop-up, and the way the backpack animates. I actually didn't mind the long process to attack - it felt like I had to rummage around in my backpack and prepare for battle, and then carefully strike with my limited resources.
I gotta say though, it was very frustrating to lose a level because of bad dice rolls. I'm curious about the option to throw away dice - was there ever any point where that's useful? Also, as much as I like using the little inventory menu I feel like having to manually grab the dice out of the chest is a bit too far, unless there was a reason that you might want to leave dice in there that I missed out on.
Great work overall though, very well polished!
