Nice take on a bullet hell game. I think the wrapping ability was nice, especially because it was a circle. The enemies had nice variety in their abilities, but I agree with other commenters that the player character could be more distinct or visible.
I was able to avoid the three starter enemies pretty easily by circling them, since they weren't any quicker than I was. The big enemy also looping was a good surprise, and it also had a lot of bullets, which was more of a challenge.
Nice job, and I'm glad you focused on simple graphics. I would have stuck to one aesthetic, or I couldn't really tell what the player character was supposed to be. The background was space, but what was I? :D
