I think this is my favorite boss so far. The way she(?) moves around ended up looking pretty cool. Her theme is fast movement and honeycomb shields!
Adding in the honeycombs makes me see how much better the game will look once I draw proper backgrounds. Oh, and the honeycombs are there to punish you for spraying bullets, and they change up the gameplay quite a bit. I might actually go back and add some bubbles to the turtle boss.
