Wow. Incredible game. Everything is so well-done here, top to bottom. The graphics (lots of juice), the sound design, the gameplay.
The incremental elements are, in my opinion, perfectly tuned. You never have to wait very long for that next dopamine hit, and each powerup makes you feel substantially powerful than the last. It's also nice that so many of the powerups feel so good to use, that I was often unsure of which one I wanted to take at each level; they're really well balanced off of each other. So satisfying to start out weak and end up as a whirling ball of death that just erases enemies on contact.
This was one of my favorite entries of the whole jam. Really scratched the itch for me, and the attention to detail is fantastic. You should be really proud of this one; great job!
