I really loved this!
Super fun variety of weapons (although I just kept maxing out my shotgun until it was firing screen-wiping waves of death) and a decent enemy variety too. Neatly stylized visuals and a very usable UI. Sound design was pretty good too, especially on the rocket. I think it's clever to use Energy as a resource for more powerful weapons, but I found that I was quickly able to trivialize it. My health also got crazy after picking up a lot of life after kill upgrades.
Overall, I'm very happy with this!
