Pretty fun! I got sucked in all the way to the end. It was a smart decision to make everything have cooldowns because it kept the basic shot relevant the whole way through. Though I'd have loved some sort of like, way to change how it worked a little over time. Like choose between bigger shot or pierces a couple enemies shot, or homing or something like that. It's always nice building up your basics. But even without that I enjoyed it quite a lot
