Great stuff, I really enjoyed this. The presentation is great. My favorite detail you had here is how you can shoot the enemy's bullets and they convert to your colour!
If you had more time to work on this, it would be fun to see the different numbers on the dice give you entirely different weapons? Maybe like 3 is a shotgun for example (of course we are limited here with the 48 hours!)
Great work, congrats on finishing and submitting, and thanks for the game!
