Happy to see someone implement the "incrementally get weaker every round for the same boss fight" as the interpretation of "sacrifice". I very much enjoyed dodging the bullet patterns and hiding behind boxes in the terrain. I only understood on reruns that the shield is not a weapon but gives you maximum health and that if you sacrifice the other two weapons you are forced to use the weaker shield. I feel maybe putting the UI for the shield in a separate area or some text could help distinguish the shield from the other standard weapons. But it was still very fun and I liked the sound design. Good job on the entry!
