Lots of fun. Physics felt solid and after a couple of minutes I was able to keep the field empty with a few lucky swings. If anything, I'd make the ball completely impervious to any impact from enemy fire, since that threw me off a lot, or I'd make the dash cost considerably less energy, since I almost never got a good moment to use it. Still, the concept and design are great and I hope you keep working and adding to it. Awesome job!
