Congratulations on completing the jam!
Using the dice rolls as damage and gate locks is a good use of the jam's theme, and the music fit well too. I would have liked to see more activity from the enemies and possibly some tradeoffs when executing a roll. Possibly splitting the roll from when the damage is applied (like giving the player 6 bullets to use instead of instantly dealing the damage) would allow the player to choose when to roll the dice and when to try to deal the damage.
Good work!
