This is a super interesting concept! I'm a pretty big bullet hell fan, but I've never seen anything like this before. The controls were well explained and felt tight and responsive, and you did a really good job spawning the bullets away from the player to ensure that they aren't instantly overwhelmed. I was also glad that the bullets clear around the player when it becomes immobile, as I probably would have died a lot more otherwise (I ended up having a high score of 3746). The difficulty curve was really clever as well, as the size makes a really big difference in the player's margin of error for dodging. The only changes I would really suggest would be having the player switch modes a bit more often and having the player move on its own when you are deflecting bullets (which I see you mentioned in the comments). Overall, really well done, I had a lot of fun with this!
