It feels extremely polished. The sprites are simple, but they come together beautifully, and everything runs so smoothly. From the gun particles to the enemy death effects. The color palette is easy on the eyes, which is impressive for a bullet hell packed with projectiles everywhere. I also really like some of the power-ups, especially things like chain projectiles and Cataclysm, which were fun to use. The dash communicates its cooldown and invulnerability clearly, and the music pairs nicely with the surprisingly calm vibe of it all.
