Space Destroyer is a good prototype that draws on the classic of fighter/space jet bullet hell games. I tried both bosses and died at both, I feel like I had a lot more fun with the twin bosses because of the bullet patterns. The movement felt good, controls were easy. I feel like you can do some exploration with size of the bullets too. Sound design was nice, and I enjoyed the music as well. A nostalgic feel for me. One special note was how the jam theme was implemented through one of the bullet patterns where previous player locations would spawn bullets that explode. Overall, well done.
