The weapon sprites pig made were made earlier on and only support wide screen, so they might stick out or not show up at regular resolutions.
I can imagine, he probably made them before Pizza Tower.
Plus I really like their abstract designs.
I am a fan of mouths that go around the whole head.
(Oh by the way, while I was swapping the music files around, I noticed an animation where Bob is used as a slot machine, and another "death" animation where they are turned into stacks. Are these in the game?)
